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: How far, in meters, has the rock moved horizontally at the moment it reaches its maximum height? B: How high above the ground, in meters, is the rock 2.42 s before it hits the ground? C: How far horizontally from the cliff, in meters, is the rock 2.42 s before it hits the ground?

There are two frogs named Froggy and Jumpy. They jumped form the top of a vertical cliff. Froggy just drop and reaches the ground in 3.50 s, while Jumpy jumps horizontally with an initial speed 95 cm/s. A. How far from the base of the cliff will Jumpy hit the ground? B. How high is the vertical cliff? C. If Jumpy jumps with an angle of 30 degrees with respect to the horizontal, what should be its initial velocity for it to land on the same spot as he did when he jumped horizontally?
