A tennis ball is thrown straight up with an initial speed of 20.0 m/s. It is caught at the same distance above the ground. How high does the ball rise (m), and how long does the ball stay in the air (s)?

I fire a tennis ball from an air cannon, straight up from ground level, at initial speed v0. At the instant it reaches the top of its trajectory, I fire a second tennis ball at the same initial speed. Air resistance is negligible.
