Question

Find the maximum height above the ground that the rocket reaches, and the greatest horizontal range of the rocket beyond point A.

A test rocket is launched by accelerating it along 200m-incline at 1.25 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 ignoring air resistance.

Answer 1

first find the resultant force and the acceleration, apply kinematics to get the velocity once at the edge of the incline.  Then treat it as a projectile motion.
