Question

3.A stone of mass 3kg is moving at a velocity of 10 m/s. If its
velocity is increased to 30 m/s, calculate the change in
momentum.​

Answer 1

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
