Question

A body of mass m moving with a speed v has kinetic energy, Ek. The body if moves with speed 2v, will have kinetic energy equal to ……………

Answer 1

initial Velocity =v

KE =EK =(1/2)m(v^2)

when velocity= 2v
KE= 2mv^2 =4EK

Answer 2

Answer:

$2m {v}^{2}$

Explanation:

hello dude==

kinetic energy =1/2mv²

and putting V=2v will get uh answer!

thanks! E=4ek)
