1. A car is parked on a cliff overlooking the ocean on an incline that makes an angle of 21 degrees below the horizontal. The driver leaves the car in neutral and it rolls from rest down the incline with a constant acceleration of 3.37 m/sE2 for a distance of 70.0 m to the edge of the cliff, which is 40.0 m above the ocean. Find the car's position relative to the base of the cliff when the car lands in the ocean in meters. Find the length of time the car is in the air in seconds.(adsbygoogle = window.adsbygoogle || []).push({});

2. A rocket is launched at an angle of 58.0 degrees above the horizontal with an initial speed of 96 m/s. The rocket moves for 3.00 s along its initial line of motion with an acceleration of 28.0 m/sE2. At this time, its engines fail and the rocket proceeds to move as a projectile. Find the maximum altitude reached by the rocket in meters. Find its total time of flight in seconds. Find its horizontal range in meters.

I figured out the x and y components in the first one but i dont know where to go from there. The situation is about the same for the next one.
