Question

the ratio of momentum to kinetic energy of a moving body is 1:2 the velocity of the particle is?​

Answer 1

Answer:

uniformly acceleration motion

Explanation:

Hope it helps

Answer 2

Answer:

let the momentum of the particle is p and kinetic energy is k then

given that p:k = 1:2

We know that

kinetic energy

k = 1/2mv^2

hence p = mv

k = 1/2p.v

k/p = v/2

hence p:k = 1:2

then k:p = 2:1

putting in equation

2/1 = v/2

v = 4 m/sec
