In a scene from a television show, a van rolls down an incline and off a vertical cliff, falling into a valley below. The van starts from rest and rolls down the incline, which makes an angle of 19.0° below the horizontal, with a constant acceleration of 3.06 m/s2. After rolling down the incline a distance of 55.0 m, it reaches the edge of the cliff, which is 40.0 m above ground level.
(a) How much time (in s) does it take the van to fall from the edge of the cliff to the landing point?
_______s
b) At the point where the van crashes into the ground, how far is it horizontally from the edge of the cliff (in m)?
____________m
