Chapter 8, Problem 1CQ
An object that has a small mass and an object that has a large mass have the same momentum. Which object has the largest kinetic energy?
Expert Solution & Answer
To determine
Which object has the largest kinetic energy?
Answer to Problem 1CQ
Largest kinetic energy will be of the smaller object.
Explanation of Solution
Given info:
An object that has a small mass and an object that has a large mass have the same momentum.
As we know the momentum is the same therefore the speed for the smaller mass object will be more. Since the kinetic energy of an object is momentum times of speed. Therefore, for the same momentum, the mass of higher speed will have more energy i.e. the smaller mass.
Therefore, the largest kinetic energy will be of the smaller object.
Conclusion
Largest kinetic energy will be of the smaller object.

You are working with a movie director and investigating a scene with a cowboy sliding off a tree limb and falling onto the saddle of
a moving horse. The distance of the fall is several meters, and the calculation shows a high probability of injury to the cowboy
from the stunt. Let's look at a simpler situation. Suppose the director asks you to have the cowboy step off a platform 2.55 m off
the ground and land on his feet on the ground. The cowboy keeps his legs straight as he falls, but then bends at the knees as
soon as he touches the ground. This allows the center of mass of his body to move through a distance of 0.660 m before his body
comes to rest. (Center of mass will be formally defined in Linear Momentum and Collisions.) You assume this motion to be under
constant acceleration of the center of mass of his body. To assess the degree of danger to the cowboy in this stunt, you wish to
calculate the average force upward on his body from the ground, as a multiple of the cowboy's…
