Question

(e) Velocity of a body of mass 50 kg is varied from 10 m.s-to 25 m.s-1 in 20 s.
(i) What is the
magnitude of force acting on the body?
(ii) What is the change in momentum of the body? ​

Answer 1

Answer:

I. 37.5

ii. 750

Explanation:

Force =m×a

here a=v/t

so 25-10/20

=15/20

=3/4

So force = 50×3/4

=75/2

=37.5

Momentum =m×v

change = mv final -mv initial

=50×25-50×10

1250-500

=750
