When a gun is fired, a very large force acts on the bullet for a very short time. The change in momentum of the bullet is given by the following relationship:
force (N) × time(s) = change in momentum (kg m/s)
(a) An average force of 4000 newton acts for 0.01 seconds on a bullet of mass 50g. Calculate the speed of the bullet. (Show your working.)
