Question

A body of mass 6kg is acted on by a force so that its velocity changes from 3m/s to 5m/s, then change in momentum is
A) 48 Ns
B) 24 Ns
C) 30 Ns
D) 12 Ns

Answer 1

Answer:

M (mass) - 6 kg

v (final velocity) - 5m/s

u (intial velocity) - 3m/s

Change in momentum = M ( v - u)

Therfore, change in momentum

= 6 ( 5 - 3)

= 6 × 2

= 12 Ns
