In the figure here, a ball is thrown up onto a roof, landing 3.40 s later at height h = 21.0 m above the release level. The ball's path just before landing is angled at 0 = 61.0° 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) o the ball's initial velocity?
