A ball rolls horizontally off a table and hits the ground. A physics students wants to calculate how long the ball is in the air Assuming air resistance is negligible, which value(s) would she need.

The height of the table. Since we are interested only in the time when ball is in the air, we will not require the width of the table.

g =9.8 m/s^2

If h is the height in meters , then the time = square root (h/9.8 )
