What is the Maximum Height a Basketball Reaches When Thrown Upward?

[swirly90]

A referee throws a basketball veritcally upward with an initial speed of 5.0m/s. Determine the maximum height above the floor reached by the basketball if it starts from a height 1.5m


How do you solve this problem? I have tried but I just don't seem to have enough information. I know acceleration due to gravity is 9.8m/s. I need at least time, initial velocity and acceleration to solve this but I really have no clue how to solve this.

The asnwer is 2.8m

An object thrown upward stops for an instant before it falls back down, so you can make a statement about the final velocity of the upward part of the motion.
