Question

A disc and a ring of same mass are rolling and if their kinetic energies are equal, then the ratio of their velocities will be

Answer 1

mass of disc =mass of ring
kinetic energy of disc =kinetic energy of ring
1/2intomass of disc into (velocity of disc)
*2upon 1/2intomass of ring into (velocity of ring) *2
(velocity of disc) *2 upon ( velocity of ring)*2

Answer 2

Answer:

v1/v2=(4/3)^1/2

Explanation:

As it is given kinetic energies are same

therefore

3/4mv1^2=mv2^2

v1/v2=(4/3)^1/2
