An airplane flying upward at 35.3 m/s and an angle of 30.0° relative to the horizontal releases a ball when it is 255 m above the ground. Calculate
(a) the time of it takes the ball to hit the ground,
(b) the maximum height of the ball, and
(c) the horizontal distance the ball travels from the release point to the ground. (Neglect any effects due to air resistance.)
