Question

The velocity of a 10 kg object decreases from 20m/s to 1
12m/s. Calculate the change in momentum.​

Answer 1

Answer:

momentum(p)= mass×velocity

initial momentum=10×20=200kgm/s

final momentum= 10×12=120kgm/s

change in momentum= 200-120= 80kgm/s

therefore the change in momentum is 80kg m/s
