1.

what will be the kinetic energy of a moving body of mass'm' and velocity 'v' if its speed increases twice?​

Answer»

Answer:

4 times

Explanation:

Kinetic energy = 1/2 m V^2

If speed INCREASES twice, v = 2V

Then kinetic energy = 1/2 m (2v)^2

= 1/2 m 4 v^2

This BECOME 4 times the actual kinetic energy.

HOPE THIS HELPS YOU..........
