The cutaway of the gun barrel shows a projectile moving through the barrel. The projectile’s exit speed is vs = 1650 m/s (relative to the barrel), the projectile’s mass is 18.5 kg, the length of the barrel is L = 4.4 m, the acceleration of the projectile down the gun barrel is constant, and θ is increasing at a constant rate of 0.18 rad/s.
Determine the following:
(a) The acceleration of the projectile.
(b) The pressure force acting on the back of the projectile.
(c) The normal force on the gun barrel due to the projectile.
