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 36.0 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?
How high does it rise above its starting point?
What is the magnitude of its velocity at the highest point?
What is the magnitude of its acceleration at the highest point?
