Question

1. A beach ball with a mass of 500 g is dropped from a height of 5 m. The wind is blowing and exerts a steady 0.8 N force horizontally on the ball. ?-? 0.8U wind force 5 m time? ? distance? ? Suppose the ball is at rest when it is dropped. (a) How much time goes by before the ball hits the ground? (b) Where does the ball hit the ground? Give the distance measured horizontally from where the ball would hit the ground with no wind. 2. An ice skater is moving 5m/s.
