A pellet of mass m moves through the smooth barrel. At the instant before the pellet emerges, its speed relative to the barrel is u. At that instant, the magnitude of the propulsive force F, which acts parallel to the barrel, is a factor of 50 times greater than the weight of the pellet. The barrel rotates about the vertical axis at angular speed Ω as the angle of elevation of the barrel is increased at the rate θ˙. Both rates are constant. Derive expressions for the acceleration term ˙u and the force the pellet exerts on the walls of the barrel at this instant.
