A golf ball is hit with a speed of 40 m/s making an angle θ above the horizontal. The ball faces an acceleration along the x-axis opposing its motion which is 15 % of the acceleration due to gravity. Calculate the value of θ so that the ball reaches a maximum horizontal distance.
Hint: use the following expression d/dθ(A•cosθ•sinθ - B•sin2θ) = A•cos(2θ) - B•sin(2θ)
