Problem
Perpendicular to plane **
A hill is sloped downward at an angle β with respect to the horizontal. A projectile is fired with an initial velocity perpendicular to the hill. When it eventually lands on the hill, let its velocity make an angle θ with respect to the horizontal. What is θ? What β yields the minimum value of θ? What is this minimum θ?
