If a horse is running at a speed of 35 m/s when it's rider pulls up on the reigns. After 5 seconds the horse slows down to a pace of 15 m/s. What is the horse's rate of acceleration?
The acceleration of the horse's speed which is running at a speed of 35 m/s when it's rider pulls up on the reigns will be -4 m/s².
What is Acceleration?Acceleration can be defined as the rate of change of velocity with respect to time. Acceleration is a vector quantity as it has both the magnitude and direction. The SI unit of acceleration is m/s² or ms⁻².
The expression for acceleration will be:
a = (v-u)/ t
v = 15m/s,
u = 35m/s,
t = 5 sec,
a = (15-35)/ 5
a = -20/ 5
a = -4 m/s²
Therefore, there will a negative acceleration of 4 meters per second square.

The sleigh is being pulled with a force of 800N and has a mass of 200 Kg.
What is the acceleration in m/s/s?
Answer:
a = 4m/s²
Explanation:
Given:
F = 800N
m = 200 kg
Unknown:
acceleration or a
Formula and solution:
a = F/m
a = 800 kg.m/s² ÷ 200 kg
Final Answer:
a = 4 m/s²
in the solution there's a two same unit and that is kg so the same unit will be cancelled and the rest is going to aapply in the answer that is 4 so if combine it the final answer is 4 m/s²
A force of 1000 pounds drags a truck 50 feet in 10 seconds.
How much work is accomplished?
How much power was required?
Work = 50, 000 ft-lbs, Power = 5000 ft-lbs/sec
Work = 50,000 ft-lbs, Power = 500 ft-lbs/sec
Work = 5,000 ft-lbs, Power = 500 ft-lbs/sec
Answer:
The first one (Work = 160,000 Nm, Power = 160, 000 Nm/sec)
Explanation:
hope this helps :)
A force of 1000 pounds drags a truck 50 feet in 10 seconds. then the work accomplished is 50000 lbs feet and the power required was 5000ft-lbs/sec.
What is Force ?Force is responsible for the motion of an object. it produces acceleration in the body. According to newton's second law force is mass times acceleration i.e. F =ma. Its SI unit is N which is equivalent to kg.m/s². There are two types of forces, balanced force and unbalanced force. Balanced forces are those forces which are opposite in direction and equal in magnitude. When Net force acting on a body is zero then we call it as balanced force. Balanced force is not responsible for the motion of the body. ex. when two persons pulling rope on both end with equal magnitude which cause them to be balanced force have 0 net force. Unbalanced forces are those when resultant of all the forces is not equal to zero is called as unbalanced force. unbalanced force is responsible for the motion of the body.
Given,
F = 1000 pound
s = 50 feet
t = 10 s
Work = F.s = 1000 * 50 = 50000 lbs feet
Power = Work/time = 50000/10 = 5000ft-lbs/sec
Hence option A is correct.

What is true about the force acting on the cars at the end of a roller coaster ride as they slow down right before stopping?
The cars will slow down as a result of unbalanced forces and negative acceleration.
What is Inertia?Inertia is the ability of an object to continue its current motion until and unless some external force causes its speed or direction to change. Inertia is described in the Newton's first law of Motion.
The cars are slowed due to negative acceleration of the object eventually to a stop, because of these unbalanced forces due to friction which are acting on them. The riders, which have inertia, are also acted on by the unbalanced forces throughout the ride causing them to change their state of motion.
