Question

Mass of body is halved and velocity is doubled the ratio of K.E will become​

Answer 1

Answer:

Mass of a body= 1/2 (acconding to the question)

now, let the velocity of body be x then the velocity is doubled so, velocity of the body is= 2x.

K.E.

$\frac{1}{2} mv {}^{2}$

K.E. =

$\frac{1}{2} \times \frac{1}{2} \times 2$

now cancelling the above equation so, we get

1/2 is the answer so, the KE. is 1:2
