if the above bowling ball rolls into a pillow and stops in 0.5s. calculate the average force exerted on the pillow

Answers

Answer 1

The average force exerted on the pillow -32 N.

Force is an external influence that can change the velocity or motion of an object.

It can also be defined as the product of mass and acceleration.Mathematically, force F = m*a

The momentum of an object is the product of its mass and velocity.

The formula for momentum is: momentum = mass x velocity

So, in the case of an 8-kg bowling ball rolling at 2 m/s, the momentum would be: momentum

= 8 kg x 2 m/s

= 16 kg m/s

To calculate the average force that the bowling ball exerts on the pillow, we can use the equation:

force = change in momentum / change in time

The change in momentum is equal to the final momentum minus the initial momentum.

Since the bowling ball is rolling at 2 m/s and stops in 0.5s,

we can assume that its final momentum is 0 (since it stops moving) and the initial momentum is 16 kg m/s.

change in momentum = final momentum - initial momentum

= 0 - 16 kg m/s

= -16 kg m/s

change in time = 0.5s

So,

force = -16 kg m/s / 0.5 s

= -32 N (Newton)

Therefore the average force exerted on the pillow is -32 N.

the question is incomplete, the complete question is "What is the momentum of an 8-kg bowling ball rolling at 2 m/s? If the bowling ball rolls into a pillow and stops in 0.5 s, calculate the average force it exerts on the pillow".

Answers

Cart A has the greatest momentum.

What is momentum?

The definition of momentum is "mass in motion." Since every item has mass, if it is moving, it must have momentum because its mass is in motion. Mass and velocity are two factors that affect momentum. According to an equation, an object's momentum is determined by multiplying its mass by its velocity.

                                                        p = mv

p = momentum

m = mass

v = velocity

Calculation:

Cart A

m₁ = 200 kg

v₁ = 4.8 m/s

p₁ = 200 × 4.8

p₁ = 960 kg-m/s

Cart B

m₂ = 200 + 20 = 220 kg

v₂ = 4 m/s

p₂ = 220 × 4

p₂ = 880 kg-m/s

Cart C

m₃ = 200 + 40 = 240 kg

v₃ = 3.8 m/s

p₃ = 240 × 3.8

p₃ = 912 m/s

Cart D

m₄ = 200 + 60 = 260 kg

A solenoid with infinite length but finite diameter is said to be infinite. In this abstraction, the solenoid is frequently seen as a cylindrical sheet of conductive material. The term "continuous" refers to the fact that the solenoid is not made up of discrete coils with finite widths but rather numerous infinitely thin coils joined together without any gaps. An indefinitely long solenoid has a homogenous magnetic field inside of it that is independent of the cross-sectional area or the distance from the axis. This is a long enough derivation of the magnetic flux density surrounding a solenoid that fringe effects may be disregarded.

Why do gas giants form further from the Sun?

The larger gas and ice giants have a tendency to form further from the Sun because the regions closer to the Sun are too warm for the lighter gases to condense there. The gas giants' primary characteristic is their extreme distance from the Sun. Because of this, these planets kept the majority of the gas and volatiles that made up the majority of the proto-solar nebula throughout the formation of the Solar System.

The position of a car at time t is given by the function p(t)=t2 2t−4. What is the velocity when p(t)=11? assume t≥0

Answers

The velocity when function p(t)=11 is 8 .

According to the question

The position of a car at time t  represented by function :

[tex]p(t)=t^{2} +2t-4[/tex]

Now,

When  function p(t) = 11 , t will be

[tex]p(t)=t^{2} +2t-4[/tex]

11 = t²+2t-4

0 = t² + 2t - 15

or

t² +2t-15 = 0

t² +(5-3)t-15 = 0

t² +5t-3t-15 = 0

t(t+5)-3(t+5) = 0

(t-3)(t+5) = 0  

t = 3 , -5  

as t cannot be -ve as given ( t≥0)

so,

t = 3

Now,

the velocity when p(t)=11

As we know velocity = [tex]\frac{position}{time}[/tex]

therefore to get the value of velocity from  function p(t)

we have to differentiate the function with respect to time

[tex]\frac{d(p(t))}{dt} =\frac{d}{dt} (t^{2} +2t-4)[/tex]

v(t) = 2t + 2  

where v(t) = velocity at that time

as t = 3 for  p(t)=11  

so ,

v(t) = 2t + 2  

v(t) = 2*3 + 2  

v(t) = 8

Explanation:

What is meant by mathematical inequality ?

The mathematical expressions with inequalities are those with unequal sides on both sides. Unlike equations, we compare two values when we work with inequality.

Here,

The total amount they have, z = $325

Amount of parking charge, x = $11

Amount for ticket cost, y = $39.25

Let the number of people who can go to the amusement park be p.

So, the expression for the inequality can be written as,

x + yp = z

Applying the values of x, y and z,

11 + 39.25p ≤ 325

39.25p ≤ 325 - 11

39.25p ≤ 314

Therefore, the number of people who can go to the amusement park,

By pascal's law, the pressure transmitted to the large piston of large area A2 will be,

                            [tex]P_2=\frac{F_2}{A_2}[/tex]

Then,

                          [tex]\frac{F_2}{A_2} =\frac{F_1}{A_1}[/tex]

How to solve the problem?We have to find the ratio of the radius of the output plunger to the radius of the input piston.We have the equation for this as,

                     [tex]\frac{A_{Plunger}}{A_{piston}} =\frac{F_{Plunger}}{F_{piston}}[/tex]

                    [tex]\frac{R_{Plunger}}{R_{piston}}=\sqrt{ \frac{F_{Plunger}}{F_{piston}}}=\sqrt{\frac{2000}{40} } =7.07[/tex]

Ec is kinetic energy, which is measured in Joules (J).m is mass measured in kilograms (kg). v is velocity measured in meters over seconds (m/s).Kinetic energy in this case

In this case, you know:

Ec= ?m=  23.2 g= 0.0232 kg (being 1 g= 0.001 kg)v= 81.9 km/h= 22.75 m/s (being 1 km/h= 0.277778 m/s)

Replacing in the definition of kinetic energy:

Ec = ½ 0.0232 g×(22.75 m/s)²

Solving:

Ec= 6.004 J

Finally, the kinetic energy of a 23.2 g object moving at a speed of 81.9 km/hr is 6.004 J.
