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?

An charge with mass m and charge q is emitted from the origin, (x,y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.
