**Compressed air is used to fire a 50g ball vertically upward from a 1.0-m-tall tube. The air exerts an upward force of 2.0N on the ball as long as it is in the tube.**

**How high does the ball go above the top of the tube?**

**I used ma=F+mg to find acceleration and came up with 30.2 m/s^2. I think from here I need to use a kinematics equation to get the velocity of the ball just as it leaves the tube, but to find the height? I only have acceleration, I don't know which equation to use.**
