A person throws two identical stones from the top of a 200-m high cliff overlooking a lake. Stone 1 is thrown at an angle of 30° above the horizontal with an initial speed of 40 m/s. Stone 2 is thrown at an angle of 30° below the horizontal with an initial speed of 40 m/s. Neglect air resistance. Immediately before they strike the water, which stone has the greater acceleration?

a. Stone 1.
b. Stone 2.
c. They have the same acceleration.

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.
