Question

A particle of mass 0.8 g is moving at a constant speed 3 x 10^2 ms Caleulate
the change in its momentum when a force of 5 N acts on it for 4 s.

Answer 1

Answer:

change in momentum = 20 kg m/s

Explanation:

change in momentum = force * t

                                     = 5 * 4

                                     = 20 kg m/s
