(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A test rocket is launched by accelerating it along a 200.0-m incline at 1.25 m/s^{2}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 is ignored). Find:

a) the maximum height above the ground that the rocket reaches

b) the greatest horizontal range of the rocket beyond point A.

2. Relevant equations

v_{x}= v_{0}cosα_{0}

v_{y}= v_{0}sinα_{0}

Basically, all the projectile motion formulas.

3. The attempt at a solution

Well, I don't even know how to start because I'm horrible at identifying which to find first. I assume I should find the initial velocity (v_{0}) of the ball, then time, then find its max. height for a). But for part b), I have no clue. And I'm confused at whether to plug in 1.25 m/s^{2}or 9.8 m/s^{2}as the acceleration. How do I get to the answer of 124 m for a) and 280 m for b) Can someone walk me through this, please?
