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.

Two masses are connected by a rope that hangs over a pulley as shown below. the pulley is a uniform cylinder of radius ํ
=0.381meters and mass ํ=3.1ํํ. initially ํ"is on the ground and ํ#rests 2.5 meters above the ground. if the system is released, use conservation of energy to determine the speed of ํ#just before it strikes the ground. assume the pulley bearing is frictionless.
