At the beginning of a basketball game, a referee tosses the ball straight up with a speed of 5.4 m/s. A player cannot touch the ball until after it reaches its maximum height and begins to fall down. What is the minimum time that a player must wait before touching the ball?
I don't understand this problem at all! Can someone help?

The max ht. occurs at V = 0.
V = Vo + gt = 0.
5.4 - 9.8t = 0
9.8t = 5.4
t = 0.55 s.
