8 1 A student pushes a textbook 1 0 m across the table using an applied force of 5 0 against a force of kinetic friction of 2 0 N The net work done on the book is a 0 0 J b 5 0 J c 10 0 J d 3 0 J e 3 0 J 2 A ball is connected to a string as shown The ball moves downward from position A with a speed vo Traveling on a circular path the ball stops at position B What enables the ball to reach point B which is above point A Ignore friction and air resistance a The work done by the gravitational force 2 The ball s initial kinetic energy The work done by the tension in the string The ball s initial gravitational potenti B A
