1. An object is thrown vertically upward from the ground and is seen to pass the top of a building with a speed of 15 m/s. If height of the building is 30 m: (a) With what velocity was the object thrown from the ground? (b) What is the maximum height reached by this object? (c) When will the object reach the ground again?
