A cannonball and a marble roll smoothly from rest down an incline. Is the cannonball's (a) time to the bottom and (b) translational kinetic energy at the bottom more than, less than, or the same as the marble's?

Explained

Explanation:

a) Cannonball and marble will reach the bottom at the same time, as acceleration due to gravity is independent of the mass of the body.

b) Translational Kinetic energy of the cannonball will be more than that of the marble as the cannonball has more mass than the marble.
