Question

when the mass and velocity of the body are doubled what happens to its kinetic energy​

Answer 1

Answer:

if mass and velocity will get double then the original kinetic energy will become eight times of itself.

Answer 2

Answer:

$ke = \frac{1}{2}mv {}^{2} \\ \ \\ when \: mass \: and \: \: velocity \\ \\ \: \: \: are \: \: doubled \: \: \: then \\ \\ new \: \: ke = \frac{1}{2} \times 2m \times 4v {}^{2} \\ \\ \\ = 8 \times \frac{1}{2} mv {}^{2} \\ \\ = 8ke (inital)$
