A problem about free fall

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 50.0m below its starting point 6.00 seconds after it leaves the thrower's hand. Air resistance may be ignored.

a.) what is the initial speed of the egg? (answer: 21.2 m/s)

b.)How high does it rise above its starting point?(answer: 22.6m)

im stuck with these two questions and i got 58m/s in the 1st part ...im reallyyy stuck
