A ball is shot from the ground into the air. At a height of 7.8 m, its velocity is = 7.21 + 7.0 m/s, with i horizontal and upward. (a) To what maximum height does the ball rise? (b) What total horizontal distance does the ball travel? What are the (c) magnitude and (d) angle (below the horizontal; give as negative) of the ball's velocity just before it hits the ground? (a) Number Units (b) Number i Units (c) Number i Units (d) Number i Units
