Question

A body of mass 3kg moving with velocity 10 m/s

Answer 1

Hence the momentum of a body is

p = m × v

p = 3 × 10

p = 30kg .m/s


Thanks

Answer 2

Answer:

The answer to your question is 60 kgm/s

Explanation:

Mass = 3kg

Initial Velocity = 10m/s

Final velocity = 30m/s

As we know,

Change in momentum = mv (final) - mv (initial)

                                    = 3*30 - 3*10

                                    = 90 - 30

                                    = 60 kgm/s
