H(t) = -16t2 + vt + s
"s" is the initial height above the ground.
But since he is ON the ground, s = 0
v is the initial velocity = 31 ft/s
H(t) = -16t^2 + 31t

This is the equation of a parabola that opens downward.
Find the vertex of the parabola and the y-coordinate of the vertex will be the maximum height.
