Question

if kE energy is 4 times what will be momentum​

Answer 1

Answer:

Twice.

Explanation:

If for a body (of constant mass), the kinetic energy is quadrupled...

Since, KE is proportional to v^2, if KE is made 4 times, the speed is doubled, that is, v -> 2v.

Since momentum is proportional to v, and v is doubled, the momentum is doubled, p -> 2p.

Note that we've assumed that the mass is constant.

Answer 2

2 times greater is the momentum
