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. The coefficient of kinetic friction between the skates and the ice is 0.1. at rut smls If the skater just glides without pushing, how far does the skater go before he or she comes to rest?

    A ball with a mass of 327 oz. is dropped down vertically from a height of 1.31 m. The speed right before the ball hit the ground was measured to be 14.5 ft/s. Assuming that the force due to air resistance is constant (and non-zero), what is the magnitude of this force? The initial velocity of the ball is zero. The direction of the force due to the air resistance is opposite to the direction that the ball is moving....
