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?
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.

- Sand from a stationary hopper falls onto a moving conveyor belt at the rate of 5.00 kg/s as shown in Figure P8.64. The conveyor belt is supported by frictionless rollers and moves at a constant speed of v = 0.750 m/s under the action of a constant horizontal external force Fext supplied by the motor that drives the belt. Find (a) the sands rate of change of momentum in the horizontal direction, (b) the force of friction exerted by the belt on the sand, (c) the external force Fext, (d) the work done by Fext in 1 s, and (e) the kinetic energy acquired by the falling sand each second due to the change in its horizontal motion. (f) Why are the answers to parts (d) and (e) different?
