A 2kg rock is thrown horizontally from the top of a building that is 20m high. The rock’s initial horizontal velocity is 5m/s. When the rock is halfway to the ground, what is the net force on it (including direction)?

How long did it take for the rock in problem 1 to hit the ground?

How far from the base of the building did the rock in problem 1 hits？
