Question

calculate the change of momentum of body of mass 5 kg when it's velocity decreased 20m/s to 0.20m/s

Answer 1

change in momentum=mv-mu
here m=5kg
u=20m/s.
v=0.20m/s
now change in momentum= 5×0.2-5×20=1-100 =. -99kgm/s

Answer 2

Here is ur answer...

=change in momentum=mv-mu
Given that
m=5kg
u=20m/s
v=0.2m/s
Change in momentum=(5x0.2-5x20)m/s kg
=(1-100)m/s kg
=-99m/s kg


Hope it helps you....
