Question

If the momentum of a body is numerically equal to 4 times of its kinetic energy then the velocity of the body is

Answer 1

Answer:

(1/2)m(kg)v^2(m/s)^2=m(kg)v(m/s)

Therefore,

(1/2)v(m/s)=1 OR

v(m/s)=2

We can read this result as velocity measured in m/s has magnitude equal to 2

Answer 2

Answer:if KE=4 MOMENTUM

1/2mv^2=4mv

V=8
