A golfer hits a golf ball with an initial velocity of 100 miles per hour. The range R of the ball as a function of the angle 0 to the horizontal is given by R(θ) = 672 sin(2θ), where R is measured in feet.

(a) At what angle θ should the ball be hit if the golfer wants the ball to travel 450 feet (150 yards)?

(b) At what angle θ should the ball be hit if the golfer wants the ball to travel 540 feet (180 yards)?

(c) At what angle θ should the ball be hit if the golfer wants the ball to travel at least 480 feet (160 yards)?
