A rock is thrown off a vertical cliff at an angle of 44.5o above horizontal. The cliff is 75.7 m high and the ground extends horizontally from the base. The initial speed of the rock is 18.4 m/s. Neglect air resistance. A: To what maximum height, in meters, does the rock rise above the edge of the cliff? B: How far, in meters, has the rock moved horizontally at the moment it reaches its maximum height? C: How long, in seconds, after being thrown does the rock hit the ground? D: How far from the base of the cliff, in meters, is the landing point of the rock?
