Question

Two wheels initially at rest roll the same distance down an inclined plane without slipping. Wheel B has twice the radius but the same mass as wheel A. All the mass is concentrated at their rims so that their moments of inertias are I = mR2.

1. Which has more translational Kinetic Energy when it reaches the bottom of the incline?

2. Which has the higher speed when it reaches the bottom of the incline?


Wheel A Wheel B Their Translational Kinetic Energies are the same. We need more information to tell.

Explanation / Answer


Their Translational Kinetic Energies are the same

speed are same
