Part : Problem Solving (12 points each) Instructions: Solve all four problems. 1. The Schwerer Gustav was a huge railway gun used in wW II. The railway gun had an unloaded mass of 1.35 x 10° kg and fired shells with a mass of 7000 kg. If both the gun and the shell were stationary to start and the shell is fired at 820 m/s, what is the recoil velocity of the gun? 2. A 850 kg car initially going...
