An egg is thrown nearly vertically upward from a point near the cornice of a tall building. It just misses the cornice on the way down and passes a point a distance 34.0 m below its starting point at a time 5.00 s after it leaves the thrower's hand. Air resistance may be ignored.

A ball is dropped from rest from the top of a cliff that is 31.2 m high. From ground level, a second ball is thrown straight upward at the same instant that the first ball is dropped. The initial speed of the second ball is exactly the same as that with which the first ball eventually hits the ground. In the absence of air resistance, the motions of the balls are just the reverse of each other. Determine how far below the top of the cliff the balls cross paths

A pebble is thrown downward from a 46.0-m-high cliff with an initial speed of 7.00 m/s. How long does it take the pebble to reach the ground?

A rock is fired straight downward from the roof of a tall building using a slingshot. If the rock leaves the slingshot with a downward velocity of 11.2 m/s, and reaches the ground with a downward velocity of 34.7 m/s, how tall is the building?  How long is the rock in the air, in seconds?
