A rock is thrown off a cliff at an angle of 51° above the horizontal. The cliff is 145 m high. The initial speed of the rock is 23 m/s. (Assume the height of the thrower is negligible.) (a) How high above the edge of the cliff does the rock rise (in m)? (b) How far has it moved horizontally when it is at maximum altitude (in m)? m (c) How long after the release does it hit the ground (in s)?
