In Fig. 4-44, a ball is thrown up onto a roof, landing 4.00 s later at height h = 20.0 m above the release level. The ball's path just before landing is angled at θ = 60.0? with the roof.

(a) Find the horizontal distance d it travels. (See the hint to Problem 41) What are the

(b) Magnitude and

(c) Angle (relative to the horizontal) of the ball's initial velocity?
