A cannon has a mass of 750 kg. The cannon is free to move backwards on wheels. The cannon fires a shell of mass 12 kg. The shell leaves the cannon horizontally at 250 m/s.
Calculate the momentum of the shell as it leaves the cannon.
Calculate the velocity of the cannon immediately after firing.
A damper is fitted to the cannon. The damper brings the cannon to rest in 1.5 s. Calculate the average force the damper exerts on the cannon.
