Question

a body having mass 10kg moving with intial velocity 20m/s and after some time it's final velocity is 54km/s, then change in momentum of the body is​

Answer 1

Explanation:

momentum = mass × velocity

intiàl momentum = mass × initial velocity

=10kg × 20m/s

=200kgm/s

final momentum = mass × final velocity

= 10kg×54m/s

=540kgm/s

Change in momentum = final momentum – initial momentum

= 540 – 200

= 340kgm/s

I hope it is correct
