From the edge of the rooftop of a building, a boy throws a stone at an angle 25.0°above the horizontal. The stone hits the ground 4.20 s later, 105 m away from the base of the building. (Ignore air resistance.)
(a) For the stone's path through the air, sketch graphs of x, y, vx, and vy as functions of time. These need to be only qualitatively correct-you need not put numbers on the axes.
(b) Find the initial velocity of the stone.
(c) Find the initial height h from which the stone was thrown.
(d) Find the maximum height H reached by the stone.
