Question

Q4) A test rocket starting from rest at point A is launched by accelerating it along a 530.0-mincline at 6.85 m/s/s. The incline rises at 25.0 degrees above the horizontal,

and at the instant the rocket leaves it, the engines turn off and the rocket is subject to gravity only (ignore air resistance). Find (a) the maximum height above the ground that the rocket reaches, and (b) the rocket's greatest horizontal range beyond point A.
