Question

In a stunt filmed for a movie, a car rolls down an incline and off a vertical cliff, falling into a valley below. The car starts from rest and rolls down the incline, which makes an angle of 18.0° below the horizontal, with a constant acceleration of 2.90 m/s². After rolling down the incline a distance of 65.0 m, it reaches the edge of the cliff, which is 45.0 m above ground level.

a)How much time (in s) does it take the car to fall from the edge of the cliff to the landing point?

b)

At the point where the car crashes into the ground, how far is it horizontally from the edge of the cliff (in m)?
