Question

a car is parked on a cliff overlooking the ocean on an incline that makes an angle of 40 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 4.00 m/s^2 for a distance of 50.0 m to the edge of the cliff, which is 30.0 m above the ocean. if the car spent 1.49s in free fall, find the cars position relative to the base of the cliff when the car lands in the ocean.

Explanation / Answer

v = root 2as = 20 m/s vx = 20 cos 40 = 15.32 m/s x = 15.32*1.49 = 22.83 m
