1. what is the mass of a 196 n weight? 2. two forces, one of 50 n due east and the other of 30 n due west are exerted on a box. what is the mass of the box if its acceleration is 4.00 m/s2? 3. a 5.00 kg object placed on a frictionless, horizontal table is connected to a string that passes over a pulley and then is fastened to a hanging 9.00 kg object. draw free-body diagrams of both objects. find the acceleration of the two objects and the tension in the string. 4. extra credit: a 1.00 kg object is observed to have an acceleration of 10.0 m/s2 in a direction 60.0° east of north. a force exerted on the object has a magnitude of 5.00 n due north. determine the magnitude and direction of the other force acting on the object

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.
