Question

28) A body is rolling down an inclined plane. Its translational and rotational
kinetic energies are equal. The body is a:
(a) solid sphere (b) hollow sphere (c) solid cylinder (d) hollow cylinder​

Answer 1

Answer:

Dec 21, 2016 - We need to assume that each object has uniform density and that they all roll ... The reason is that would be the one tying up the least kinetic energy in its rotation. .... A) A Solid sphere B) A hollow sphere C) Solid cylinder D) A hollow cylinder ... a ring and a circular disc of identical radii are rolling down an inclined plane ...
