Chapter 4, Problem 48(choose chapter or problem)
In Fig. 4-41, 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 \(\theta=60.0^{\circ}\) with the roof.
(a) Find the horizontal distance d it travels. (See the hint to Problem 39.) What are the
(b) magnitude and
(c) angle (relative to the horizontal) of the ball’s initial velocity?
