A car is parked on a steep incline, making an angle of 37.0° below the horizontal and overlooking the ocean, when its brakes fail and it begins to roll. Starting from rest at t = 0, the car rolls down the incline with a constant acceleration of 4.23 m/s2, traveling 53.0 m to the edge of a vertical cliff. The cliff is 30.0 m above the ocean.
(a) Find the speed of the car when it reaches the edge of the
cliff.
m/s
(b) Find the time interval elapsed when it arrives there.
s
(c) Find the velocity of the car when it lands in the ocean.
| magnitude | m/s |
| direction | ° below the horizontal |
(d) Find the total time interval the car is in motion.
s
(e) Find the position of the car when it lands in the ocean,
relative to the base of the cliff.

A car is parked on a cliff that slopes downward by 18.7° below the horizontal. The brakes give out and the car rolls from rest down the cliff. It leaves the edge of the cliff at 21 m/s. The edge of the cliff is 15 m above the ocean. What is the car’s horizontal position relative to the base of the cliff at the instant the car strikes the water? Take the acceleration of gravity to be 9.8 m/s. Can...
