Question

In an online viral video, a truck rolls down an incline and off a vertical cliff, falling into an ocean below. The truck starts from rest and rolls down the incline, which makes an angle of 22.0° below the horizontal, with a constant acceleration of 3.52 m/s². After rolling down the incline a distance of 70.0 m, it reaches the edge of the cliff, which is 30.0 m above the ocean.

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

(b) At the point where the truck lands in the ocean, how far is it horizontally from the edge of the cliff (in m)?
