Two wheels initially at rest roll the same distance without slipping down identical inclined planes starting from rest. Wheel B has twice the radius but the same mass as wheel A. All the mass is concentrated in their rims, so that the rotational inertias are I = mR2
.Which has more translational kinetic energy when it gets to the bottom?
BLUE: Wheel A
PINK: Wheel B
PURPLE: The kinetic energies are the same.
YELLOW: need more information
