Homework Help: Physics

Posted by Jerry on Thursday, September 13, 2012 at 2:41pm.

From the edge of the rooftop of a building, a boy throws a stone at an angle 20.0° above the horizontal. The stone hits the ground 4.60 s later, 104 m away from the base of the building. (Ignore air resistance.)

What is the maximum height H reached by the stone?

(I found that the velocity is 24.06 and the initial height is 65.834, but I cant get the maximum height right.)
