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
