A ball is thrown up onto a roof, landing 4.50 s later at height h = 20.0 m above the release level. The ball's path just before landing is angled at θ = 54.0˚ with the roof. (a) Find the horizontal distance d it travels. What are the (b) magnitude and (c) angle (relative to the horizontal) of the ball's initial velocity?
