Question

A body of mass 6 kg is acted on by a force so that its velocity changes from 3 m/s to 5 m/s, then change in
momentum is
(1) 48 Ns
(2) 24 Ns
(3) 30 Ns
(4) 12 Ns​

Answer 1

change in momentum is

mv-mu

change in momentum= 6×5 - 6×3

change in momentum = 30 -18

change in momentum = 12kgm/s

Answer 2

Answer:

Answer is 12 Ns

Explanation:

Momentum (m) = 6 kg

initial velocity (u) =3 m/s

final velocity (v) = 5m/s

Change in momentum = mv -mu

=6×5 - 6×3

=30-18

= 12Ns
