Abstract

Place one end of a rod on the floor and drop it, along with a ball, originally placed at a height equal to the free end of the rod. Which one, if either, has the larger speed when it hits the ground: the free end of the rod or the ball? In this work are presented several solutions, in increasing levels of complexity. We conclude that such questions can help the development of investigative activities in the classroom environment, and eventually lead some students to technology careers.
