Question

2. Calculate the change in momentum of an object having mass 20g moving with velocity 15m/s which eventually comes to rest.​

Answer 1

Answer:  -0.3kgm/s

Explanation:

u=15m/s      v=o               m=20g=20*1/1000=0.02kg

change in momentum=final momentum-initial momentum

=mv-mu

=0.02*0-0.02*15

=-0.3kgm/s
