A cannon of mass m slides down a smooth inclined plane forming the angle a(alpha) with the horizontal. At the moment when the velocity of the cannon reaches v, it fires a shell in a horizontal direction with the result that the cannon stops and the shell "carries away" the momentum p. Suppose that the firing duration is equal to t. What is the reaction force R of the inclined plane averaged over the time t?
