Atoy rocket is launched (from rest) horizontally off a 100m tall cliff. the rocket produces a constant horizontal thrust of 2.0m/s^2. the wings on the rocket creates an upward lift equivalent to 1.8m/s^2. ignore air resistance. (a) how long does the rocket stay in the air?
(b) how far does the rocket travel from the cliff?
(c) what is the magnitude and angle of the velocity as it hits the gorund?

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.
