An object of mass 100kg is accelerated uniformly from a velocity of 5m...
Mass =100kg
time =6sec
final velocity (v) =3m/s
initial velocity (u) =5m/s
final momentum =3*100=300kgm/s
initial momentum =5*100=500kgm/s
force = change in momentum /time
F=mv-mu/t
F=300-500/6
F=-200/6
F=-33.3
minus symbol denotes that force is applied in opposite direction
