Im having some problems with this question. Some help would be nice. Thanks.

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 50.0 m below its starting point at a time 5.00 s after it leaves the thrower's hand. Air resistance may be ignored.

What is the initial speed of the egg?

Do you have any equations, or a textbook that goes trough similar problems in the text etc?

Conservation of energy, kinematic relationsships etc?

Do you know the value and direction of acceleration at the different parts of the eggs motion?
