The straight, red line represents the motion of a swimmer who swam 800 m during each 10-min period. Her speed was constant at 80 m/min. The straight blue line represents the motion of a swimmer who s ...

... i. An object which is moving rightward has a rightward force acting upon it. Answer: False An object which is accelerating rightward must have a rightward force and a rightward net force acting upon it. But an object which is merely moving rightward does not necessarily have a rightward force upon i ...

... answer: We’ll use Fnet t = p. Since the ball changes direction, p = m v = m (vf - v0) = 1.3 [22 - (-13)] = (1.3 kg) (35 m/s) = 45.5 kg · m /s. Thus, t = 45.5 / 1200 = 0.0379 s, which is just under 40 ms. During this contact time the ball compresses substantially and then decompresses. This hap ...
