Q.1: Determine the net force acting on each of the following objects. In each case assume that all forces acting on the object are given. K (a) At an instant when a soccer ball is slightly off the ground, a player kicks it, exerting a force of 28 N at 50.0 above the horizontal. The force of gravity acting on the ball is 3.2 N [down]. (b) Two children pull a sled across the ice. One child pulls with a force of 10 N [N 35 E], and the other pulls with a force of 28 N [N 54 W]. There is negligible friction acting on the sled. (c) In a circus act, a performer with a force of gravity of 4.2 x 102 N on her is lifted by two different ropes at the same time. One rope exerts a tension of 4.3 x 102 N [up and 35 left], and the other rope exerts a force of 3.2 x 102 N [up].
