Question

what will happen to the kinetic energy if its mass is doubled and velocity is half​

Answer 1

Answer:

Mark it as brainliest

Yes

Explanation:

KE = 1/2 * mass * v²

Thus velocity will become 1/4 and mass will become twice

Thus kinetuc energy will be 1/2

Answer 2

We know,

Kinetic Energy, K = (mv²)/2

Let 'm' and 'v' be replaced by '2m' and 'v/2' respectively in the RHS of the equation, then the RHS will be,

((2m)(v/2)²)/2

(2mv²/4)/2

(mv²/2)/2

This means the kinetic energy will be halved.
