Question

By how much does the momentum of a body of mass 5kg change when its speed. Decreases from 0.2m/s and increase from 30m/s to 40m/s​

Answer 1

Answer:

Momentum, p= mv

You can either find momentum in each case and then subtract final from initial to get the change in momentum.

Or,

Change in momentum = m(v1 - v2)

= 5 x (40 - 30) = 50 kgm/s
