Question

Calculate the momentum of atoy car of mass 200g moving with with aspeed of 5m/s.

Answer 1

Momentum of the toy car= Mass of the car * Velocity of the car

=200/1000(converting g to kg)*5

=(1/5)*5

=1 kgm/s

Therefore, the momentum of the car is 1 kgm/s.

Answer 2

  momentum =mass into  velocity   p=mv. here m=200g. and v=50m/s therefore p=200*50that is 20000m
