A man walks 20.0km South and then 8.00km  35.0oN of W. a) What is the man’s displacement ?  (16.7km,  67o S of W) b) What is the man’s average speed if the entire trip takes 12.0 hours ?  (2.30km/hr) c) What is the man’s average velocity ?  (1.40km/hr,  67o S of W)

Two metal balls collided with other and moved away in oppo direction. The silver metal ball v 185N and the gold metal ball w 160 N. Given that the first ball ho velocity of 2.50(m)/(s), what is the velocity of the second ball?

Which statement is true? O Average velocity can be zero when average speed is not. O Average velocity is always positive. O Speed describes how fast and in what direction an object is moving. O Average speed is the same as average velocity
