mass of body,m= 5kg
u=30 m/s
momentum= m*u =5*30=150 kgm/s
v=40m/s
final momentum=m*v=5*40=200 kgm/s
increase in momentum=final momentum-momentum=200-150=50kgm/s
u=30 m/s
momentum= m*u =5*30=150 kgm/s
v=40m/s
final momentum=m*v=5*40=200 kgm/s
increase in momentum=final momentum-momentum=200-150=50kgm/s
