Question

a body of mass m which is moving with certain velocity has kinetic energy E. if the same body moves with double the initial velocity then it's kinetic energy becomes​

Answer 1

Answer

I this case it's kinetic energy will become double

If

K=V

If V=2v

Then

K2=2v

Answer 2

Answer:

Explanation:Assume velocity as x if doubles 2x

So ke=1/2m4x^2=m2x^2
