A rifle, which has a mass of 5.50 kg, fires a bullet, which has a mass of m=65.0grams, at a ballistic pendulum. The ballistic pendulum consists of a block of wood, which has a mass M = 5.00 kg, attached to two strings of length L=1.25m. When the block is struck by the bullet, the block swings backward until the angle between the ballistics pendulum and the vertical reaches a maximum angle of 38. Note: There are 2 parts to this problem: collision (before to immediately after) followed by the swinging of pendulum. MR U Lcos38 m Before collision 38 M After Collision L E h h=0 a) Determine the maximum gravitational potential energy of the ballistic pendulum-Earth system when it reaches its maximum angle.
