a new cannon was being developed in a science lab. the instructor wanted to do some testing of the cannon's ability to launch objects with different masses. the instructor used tennis balls and filled them with lead, rocks, and styrofoam. the fourth tennis ball had nothing in it. the instructor fired each tennis ball with the same speed and measured the kinetic energy of each over a period of one second.
