Physics student standing on the edge of a cliff throws a stonevertically downward with an initial speed of 10.0 m/s. The instantbefore the stone hits the ground below, it is traveling at a speedof 30.0 m/s. If the physics student were to throw the rockhorizontally outward from the cliff instead, with the same initialspeed of 10.0 m/s, what is the magnitude of the velocity of thestone just before it hits the ground?

Many machines- including inclined planes such as ramps- increase the strength of the force put into the machine but decrease the distance over which the force is applied. true or false

The free body diagram shows a box being pulled to the left up a 25-degree incline. the magnitude of the normal force is

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.
