The 200-mm-diametcr gas gun is evacuated on the right of the 8-kg projectile. On the left of the projectile, the tube contains gas with pressure p0 = 1 times 105 Pa (N/m2). The force F is slowly increased, moving the projectile 0.5 m to the left from the position shown. The force is then removed, and the projectile accelerates to the right. If you neglect friction and assume that the pressure of the gas is related to its volume by pV = constant, what is the velocity of the projectile when it has returned to its original position?
