Arifle, which has a mass of 5.50 kg., is used to fire a bullet, which has a massof m = 65.0 grams., at a "ballistics pendulum". the ballistics pendulum consistsof a block of wood, which has a mass of m = 5.00 kg., attached to two stringswhich are l = 125 cm long. when the block is struck by the bullet the blockswings backward until the angle between the ballistics pendulum and thevertical reaches a maximum angle ofa= 38.0o. a. what will be the maximum gravitational energy contained in the ballisticspendulum when it reaches the maximum angle? b. what was the velocity of the block of wood immediately after being struck bythe bullet? c. what was the velocity of the bullet immediately before it strikes the block ofwood? d. how much work was done by the bullet as it lodged in the block of wood? e. what will be the recoil velocity of the rifle? f. how much energy was released when the bullet was fired?
