Question

A solid sphere, disc and solid cylinder all of the same mass
and made of the me material are allowed to roll down (from
rest) on the inclined plane, then find the ratios of their kinetic
energies​

Answer 1

Answer:

Work - energy theorem: Wall forces = Δ K.E mgh = K.E all will have same K.E. at the bottom.Also, mgh = 12Iw^2 + 12mv^2 mgh = 12 × Kmr^2w^2 + 12mv^2 ...
