A car is parked on a cliff overlooking the ocean on an incline that makes an angle of 17.0° below the horizontal. The negligent driver leaves the car in neutral, and the emergency brakes are defective. The car rolls from rest down the incline with a constant acceleration of 2.75 m/s2 for a distance of 70.0 m to the edge of the cliff, which is 40.0 m above the ocean.
(a) Find the car's position relative to the base of the cliff when the car lands in the ocean.
m
(b) Find the length of time the car is in the air.
