**1. Homework Statement**

A small ball rolls horizontally off the edge of a tabletop that is 1.22 m high. It strikes the floor at a point 1.58 m horizontally away from the edge of the table. (a) How long is the ball in the air? (b) What is its speed at the instant it leaves the table?

**2. Homework Equations**

Unknown

**3. The Attempt at a Solution**

So far all I've been able to calculate is the distance from the tabletop to the position on the floor that it landed. = 1.99m. Is there some equation with a trig function in it to get the time the ball is in the air?
