A car is parked on an incline of 15.6 degrees below the horizontal, the brakes fail and it rolls down the incline 27.5m and off the edge of a cliff that is 57m above the ground. Find the car's position when it its the ground relative to the base of the cliff.
rather than type them all out, I'll just say kinematics.
The Attempt at a Solution
I know you have to break the gravity vector up into components so I took -9.8 sin(15.6) = -2.63 m/s^2. I keep calculating the average speed of the car, not the speed at the point it goes off the cliff. Please help, thanks!
