Next, we use the fact that in order for the velocity vector to exactly horizontal, we must have v I z = ˙ z ( t f )=0 . Thus, we have ˙ z ( t f )= eV sin θ gt f =0 = eV sin θ = gL V cos θ Solving for L , there follows L = e V 2 g sin θ cos θ It is helpful to combine the equations for t f and L , which yields t f = eV g sin θ The ball’s height when it reaches the upper surface is
