The parking brake on a car fails resulting in the car rolling from rest down a hill. The car then rolls off of a cliff into the ocean as pictured below. The hill that the car was parked on makes an angle of 35.0 degree with the horizontal and is 40.0 m long. The vertical distance from the bottom of the hill to the water is 75.0 m. Determine the distance the car will land from the base of the cliff.
