A car is parked on a cliff overlooking the ocean
on an incline that makes an angle of 17.0 degrees
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 2.50 m/s^2 and travels 46.0 m to the edge of
the cliff. The cliff is 26.0 m above the ocean.
The acceleration of gravity is 9.81 m/s^2 :
a) How long is the car in the air? Answer
in units of s.
b) What is the car's position relative to the
base of the cliff when the car lands in the
ocean? Answer in units of m.

Try solving it by dividing the question to 2 parts, horizontal and vertical and it will be easier.
Hope it helps!

Approximately 2 seconds. Without knowing the coefficient of friction it would be hard to say how far from the cliff it would land. Ignoring the coefficient, it would be safe to say that it would be less than 30 meters.
