Question

A body of mass 20 g is moving at 5 m/s if the velocity increases to 20 m/s find change of momentum and impulse​

Answer 1

Answer:

mass= 20 g=(20/1000)kg

velocity= 5m/s

momentum= m x v

(20/1000) x 5= 0.1Ns

new velocity= 25 m/ s

new momentum= (20/1000) x 25=0.5

change in momentum= 0.5-0.1= 0.4 Ns
