An experiment consists of releasing a metallic sphere from rest from the top of a vertical tube of length l, and at the same instant, a popgun located at the bottom of the tube fires a ping-pong ball at a speed of 5 m/s. Determine the greatest length the tube can have in order for the collision to take place before the ping pong ball hits the bottom of the tube.
