Question

A force of 10 N IS acting on a body of mass 20 kg for 10 seconds. change in
momentum is
(A) 5 kg m/s
ve) 100 kg m/s
(B) 200 kg m/s
(D) 1000 kg m/s​

Answer 1

Explanation:

First calculate acceleration a = F/m = 10/20 = 0.5 m/s2

Then change in velocity ∆v = at = 0.5 × 10 = 5 m/s

change in moment ∆p = m∆v = 20 × 5 = 100 kg m/s

Answer 2

Answer:

answer is 100 kg m/s
