The Army of the Nation of Whynot has a plan to propel small vehicles across the battlefield by shooting them, from behind, with a machine gun. They've hired you as a consultant to help with an upcoming test. A 200 test vehicle will roll along frictionless rails. The vehicle has a tall "sail" made of ultrahard steel. Previous tests have shown that a 20.0 bullet traveling at 300 rebounds from the sail at 200 . The design objective is for the cart to reach a speed of 18.0 in 30.0 . You need to tell them how many bullets to fire per second from the machine gun. Note that your answer should be a rate, which can be fractional, rather than a quantity, which must be an integer. A five-star general will watch the test, so your ability to get future consulting jobs will depend on the outcome.
