A car is parked on a cliff overlooking the ocean on an incline that makes an angle of 35.0 degrees below the horizontal. the negligent driver leaves the car in neautral, and the emergency brakes are defective. The car rolls from rest down the incline with a constant acceleration of 3.00 m/s^2 for a distance of 60.0m to the edge of the cliff, which is 40.0m above the ocean.
find (a) the car's position relative to the base of the cliff when the car lands in the ocean and
find (b) the length of time the car is in the air.
