To find how long the ball is in the air, we need to solve for t by using the quadratic formula or other methods that can be used to solve quadratic equations. 

I got x= -1/16 and x=3 as the solutions. However, -1/16 doesn't make sense in this situation because the ball can't stay in the air for -1/16 seconds. Thus, your answer is 3 seconds.
