**Scott**, Thursday, September 13, 2012 at 2:02pmthe vertical component of the velocity (Vv)is __ 20.0 * sin(32.0º)

the horizontal component (Vh) is __ 20.0 * cos(32.0º)

the time (T) to max height is __ Vv / g

a) Hmax = (-.5 g T^2) + (Vv * T) + 1.1

b) at Hmax, the ball has no vertical velocity; only horizontal (Vh)
