A car of mass 1500kg is brought to rest from a velocity of 25m/s by a constant force of 3000N. Determine
the change in momentum produced by the force and the time it takes the car to come to rest.

?P=mv-mu=1500(0-25)=-37500kgm/s.
Ft=?P
We ignore the negative sign in this part because time is a scalar quantity.
3000*t=37500
t=37500/3000 =15.5seconds.
