A rock is thrown off a cliff at an angle of 53° with respect to the horizontal. The cliff is
100 m high. The initial speed of the rock is 30 m/s. (a) How high above the edge of the

cliff does the rock rise? (b) How far has it moved horizontally when it is at maximum
altitude? (c) How long after the release does it hit the ground? (d) What is the range of
the rock? (e) What are the horizontal and vertical positions of the rock relative to the edge
of the cliff at t = 2. 0 s, t = 4. 0 s, and t = 6. 0 s?
