Answer:

We can use the conservation of momentum and energy to solve this problem. Since the collision is perfectly elastic, both momentum and kinetic energy are conserved.

Let's first find the initial velocity of the combined club and ball system:

m_clubhead = 220 g = 0.22 kg  (effective mass of the clubhead)

m_ball = 46.0 g = 0.046 kg

v_clubhead = 45.0 m/s

The initial momentum of the system is:

p_i = m_clubhead * v_clubhead = 0.22 kg * 45.0 m/s = 9.90 kg·m/s

Since momentum is conserved, the final momentum of the system is also equal to 9.90 kg·m/s:

p_f = m_clubhead * v_clubhead' + m_ball * v_ball'

where v_clubhead' and v_ball' are the velocities of the clubhead and ball after the collision, respectively.

The initial kinetic energy of the system is:

KE_i = 1/2 * m_clubhead * v_clubhead^2 = 0.5 * 0.22 kg * (45.0 m/s)^2 = 222.75 J

Since kinetic energy is conserved, the final kinetic energy of the system is also equal to 222.75 J:

KE_f = 1/2 * m_clubhead * v_clubhead'^2 + 1/2 * m_ball * v_ball'^2

Now we can solve for v_ball':

p_f = m_clubhead * v_clubhead' + m_ball * v_ball'

9.90 kg·m/s = 0.22 kg * v_clubhead' + 0.046 kg * v_ball'

KE_f = 1/2 * m_clubhead * v_clubhead'^2 + 1/2 * m_ball * v_ball'^2

222.75 J = 0.5 * 0.22 kg * v_clubhead'^2 + 0.5 * 0.046 kg * v_ball'^2

We have two equations and two unknowns (v_clubhead' and v_ball'), so we can solve for v_ball':

v_ball' = (p_f - m_clubhead * v_clubhead') / m_ball

Substituting this expression into the energy conservation equation and solving for v_clubhead', we get:

v_clubhead' = sqrt(2/m_clubhead * (m_ball * v_ball'^2 + KE_i - KE_f))

Now we can use this equation to answer the questions:

(a) With the given data, we get:

v_ball' = (9.90 kg·m/s - 0.22 kg * 45.0 m/s) / 0.046 kg = 93.70 m/s

v_clubhead' = sqrt(2/0.22 * (0.046 kg * (93.70 m/s)^2 + 222.75 J - 222.75 J)) = 45.0 m/s

Therefore, the ball leaves the tee with a speed of 93.70 m/s.

(b) If we double the mass of the clubhead, the effective mass becomes 440 g = 0.44 kg, and the initial momentum of the system doubles to 19.80 kg·m/s. Using the same equations as before, we get:

v_ball' = (19.80 kg·m/s - 0.44 kg * 45.0 m/s) / 0.046 kg = 187.41 m

Explanation:

If we assume the same efficiency, then we can use Amdahl's Law to calculate the new runtime on 16 cores.

Amdahl's Law states that the speedup of a parallel program is limited by the portion of the program that must be executed sequentially. In this case, the portion that must be executed sequentially is (80-20)/80 = 0.75 or 75%. This means that only 25% of the program can be parallelized. Therefore, the speedup we can expect from doubling the number of cores is limited to 1/((1-0.25) + 0.25/8) = 1.85.
Using this speedup, we can calculate the new runtime on 16 cores as 20/1.85 = 10.81 seconds.

The change in the system's kinetic energy of the 950-kg satellite orbiting the earth at a constant altitude of 90 km is zero.

This is because the satellite is orbiting at a constant altitude, meaning its distance from the Earth's center is constant, and therefore, its potential energy remains constant.  When the altitude is constant, there is no change in the system's kinetic energy, as the satellite maintains the same speed and distance from the Earth. Therefore, the change in kinetic energy is 0. Since the total energy of a satellite in orbit is constant, any change in potential energy is compensated by an equal and opposite change in kinetic energy. Therefore, since the potential energy is constant, the kinetic energy must also be constant.

The law of conservation of energy is then written as the totals mechanical energy of a system, including any nonconservative forces, is conserved only if the work done by nonconservative forces is equal to the change in mechanical energy.

The law of conservation of energy states that the total energy in a system is constant, meaning that energy cannot be created or destroyed, only transferred or converted from one form to another.

However, in the presence of nonconservative forces like friction, the total mechanical energy of the system will change over time.

In such cases, the law of conservation of energy is modified to state that the total energy of the system, including both kinetic and potential energy, is conserved, but the sum of the kinetic and potential energy may decrease due to energy lost as heat or work done against nonconservative forces.

The question is asking for the work done on the athlete by the pushing force of the pole. The pushing force that the pole exerts back on the athlete is given as an external force. The work done by an external force is calculated using the formula W = Fd, where W is work, F is force, and d is the distance over which the force acts. In this case, the pushing force of the pole is given as an external force of unknown magnitude, but we are given the distance over which it acts, which is 0.20 meters. Therefore, we can use this distance along with the formula W = Fd to calculate the work done on the athlete:
W = Fd

We don't know the value of F, so we cannot solve for W directly. However, we do know that the pushing force of the pole is equal and opposite to the force exerted by the athlete on the pole. This is because of Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. So, we can assume that the force exerted by the athlete on the pole is also equal in magnitude to the pushing force of the pole, but in the opposite direction. Therefore, we can rewrite the formula for work as:
W = -Fd
where the negative sign indicates that the work done is in the opposite direction to the force.
Now, we can substitute the given values into the formula to find the work done on the athlete:
W = -(F)(0.20)

We don't know the value of F, but we can assume that it is a positive value since the pole is pushing back on the athlete. Therefore, the negative sign in the formula will make the work done negative, indicating that it is in the opposite direction to the pushing force of the pole. Without knowing the value of F, we cannot calculate the exact amount of work done on the athlete. However, we can say that the work done will be negative and proportional to the magnitude of the pushing force of the pole, multiplied by the distance over which it acts.

The boxes are identical and they have the same mass. Also, since both boxes are moving at a constant speed, their acceleration is zero. Therefore, the force that Alice is applying to the box is also 55 N.

To find the magnitude of the force that Alice is applying to the box, we need to use the equation: force = mass x acceleration

Since both boxes are identical, they have the same mass. Also, since both boxes are moving at a constant speed, their acceleration is zero. Therefore, the force that Alice is applying to the box is also 55 N.

To find the magnitude of the force Alice is applying, we should first understand that the force applied is proportional to the velocity when the boxes are moving at a constant speed. Since Alice's box moves at 2.2 m/s and Bob's box moves at 1.1 m/s, Alice's box is moving twice as fast as Bob's box.

To maintain this constant speed, the force applied must also be doubled. Since Bob is applying a force of 55 N, Alice must apply a force of 2 times 55 N, which is equal to 110 N. Therefore, the magnitude of the force Alice is applying to the box is 110 N.

When a mass hangs from the ceiling by a string and the mass is doubled, the travel time for a wave pulse traveling from the mass to the ceiling and back does not decrease by any factor.

The travel time for a wave pulse traveling from the mass to the ceiling and back depends on the length of the string and the gravitational force acting on the mass. If the mass is doubled, the gravitational force acting on it will also double. This will cause the string to stretch and become slightly longer, resulting in a longer travel time for the wave pulse. Therefore, the travel time will not decrease by any factor, but will actually increase slightly due to the increased gravitational force and stretching of the string.

When a mass hangs from the ceiling by a string and the mass is doubled, the travel time for a wave pulse traveling from the mass to the ceiling and back does not decrease by any factor. This is because the wave speed on the string depends only on the tension in the string and its linear mass density, and not on the mass of the object hanging from it.
