Question

If two bodies have masses in the ratio 1:2 , have their speed in
the ratio 4:5 , find the ratio of their kinetic energies?

Tulsi Mehta · Answer

let the masses be 1x and 2x and let speed(velocity) be 4y and
5y
required ratio = (1/2mv​2)1/
(1/2mv2)2 = (1/2 * x* 16y2)/ (1/2
* 2x *25y2) (((( * means multiplication))))
=16/25
= 16:25
