Question

If the linear momentum of any body 4 k.g. m/sec. then find the velocity of the body if the mass of the body is 2 k.g.​

Answer 1

Answer:

If m be the mass of the body and p be the momentum of the body, the kinetic energy of the body is

KE= 2mp 2

= 2(2)4 2

=4J

Answer 2

Explanation:

Momentum= mass×velocity

P=mv

v=P/m=4kgm/s÷2kg=2m/s.

Velocity of the body is 2m/s.
