A 16.0 N B 62.5 N C 100 N D 160 N 7 A ball is dropped onto horizontal ground and bounces vertically upwards. When the ball is in contact with the ground, the following forces are present:  the weight W of the ball  the contact force P exerted on the ground by the ball  the contact force N exerted on the ball by the ground. At a particular instant, the ball is in contact with the ground and the ball is momentarily stationary. At this instant, which relationship is correct? A N = P + W B N = P C N = W D W = P ball ground

4 8 Which statement concerning the mass of a body is correct? A Mass is a measure of the gravitational pull on the body. B The mass of the body is a measure of the body’s resistance to a change in motion. C The SI unit of mass is the gram. D When gravitational field strength changes, the mass of the body changes. 9 A uniform beam of weight 30 N has a length of 100 cm. A box of 15 N is placed at the 20 cm mark.
