A test rocket is launched by accelerating it along a 200.0 m incline at 1.78 m/s2 starting from rest at point A. The incline rises at 35.0 above the horizontal, and at the instant the rocket leaves it, its engines turn off and it is subject only to gravity (air resistance can be ignored). a) Find the maximum height above the ground that the rocket reaches b) Find the greatest horizontal range of the rocket beyond point A (point A is located at the base of the incline)
