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.

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
