Homework Help: physics

Posted by courtney on Wednesday, January 16, 2008 at 6:17pm.

A ball is thrown vertically upwards with an initial velocity of 20.96 m/s. Neglecting air resistance, how long is the ball in the air? What is the greatest height reached by the ball?

this problem seems easy enough but I can't seem to get the answer. How can I get time using only velocity?
