a ball is thrown up onto a roof, landing 4.70 s later at height h = 24.0 m
above the release level. The ball's path just before landing is angled at � = 62.0° with the roof.
(a) Find the horizontal distance d it travels. (Hint: One way is to reverse the motion, as if it is
on a video.) What are the (b) magnitude and (c) angle (relative to the horizontal) of the ball's
initial velocity?
