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

A car is parked on a cliff overlooking the ocean on an incline that makes an angle of 24 degrees below the horizontal. The parking break is defective, so the car rolls from rest down the incline with a constant acceleration on 4m/s^{2}and travels 50m to the edge of the ocean. The cliff is 30 m above the ocean.

a. What is the car's horizontal position relative to the base of the cliff when it lands in the ocean?

b. How long is the car in the air?

2. Relevant equations

Vy^{2}= -2gΔy

Δy = -1/2g(Δt)^{2}

Vy= -gΔt

Vx = Δx/Δt

3. The attempt at a solution

Δt = square root (30sin(24)/(1/2)g) = 2.5s

However, I don't really think that's right. If someone could explain the process of solving the overall of equation, that would be extremely helpful.
