[SOLVED] Physics again 1. The problem statement, all variables and given/known data A small ball rolls horizontally off the edge of a tabletop that is 1.19 m high. It strikes the floor at a point 1.78 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. Relevant equations x=vcos(x)t y=vsin(x)t- .5gt^2 3. The attempt at a solution I believe those are the right equations that I need, but I have two unknowns in the equation, velocity and time.
