If the speed of a vehicle increases by 22%, by what factor does its kinetic energy increase?

The kinetic increases by 48.84 %

Explanation:

The expression for the kinetic energy is:-

Where, m is the mass of the object

v is the velocity of the object

Let the new velocity is:- v'

v is increased by 22 %. Thus, v' = 1.22 v

So, the new kinetic energy is:-

Thus, the kinetic increases by 48.84 %
