Rachel is on the roof of a building, h=15 memters above ground. She throws a heavy ball into the air with a speed v=2.6m/s at an angle 62 degree with respect to the horizontal. Ignore air resistance.

a) Find the speed of the ball when it hits the ground.

b) for what value (s) of the angle is the speed of the ball greatest when it hits the ground.
