Problem
A golfer is playing golf facing an inclined plane of inclination angle θ as shown in the figure. When he strikes the ball, the ball flies towards the inclined plane. The ball left the ground at an angle φ relative to the inclined plane. What is the value of φ at which the ball can land the farthest distance along the incline? Neglect air resistance and assume the inclined plane is infinitely long.
