Take down as positive. A car is parked near a cliff overlooking the ocean on an incline that makes an angle of 10.5 degrees with the horizontal. The negligent driver leaves the car in neutral, and the emergency brakes are defective. The car rolls from rest down the incline and has a velocity of 20m/s when it reaches the edge of the cliff. The cliff is 15.1 m above the ocean. The acceleration of gravity is 9.8m/s2. How far is the car from the base of the cliff when the car hits the ocean? Answer in units of m.
I think I know how to solve the problem, but I'm unsure as to whether the 20m/s they are referring to is the x-component, or the speed, in which case I would need to find the x and y components to solve the problem. I know that in a different scenario, if someone was running then slipped off a cliff that was level, the velocity they were at when they slipped off the cliff would be their x component. But in this case, the car is rolling off an incline... Would it be the same as the other situation?
