Homework Help: Physics...help please!

Posted by Cecille on Friday, February 11, 2011 at 3:46pm.

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. At what fraction of the maximum height reached by the
first ball do the two collide?
