Question

A car and bus has same kinetic energy and their velocities are equal . Is their any difference in their mass , what is the ratio between their masses?

Answer 1

There will be no difference in their masses as

$ke = 1 \div 2 \times m {v}^{2}$

Then by dividing kinetic energy of both bus and car we will get their masses equal.

So,the ratio of their masses will also be equal.
