1. The problem statement, all variables and given/known data I have a project for physics that requires me to construct a self-contained egg moving device, that must use falling masses to power it. It must move itself 1.5m, then pick up an egg (in an egg cup holder) off of a standard sized paint can, then move another meter and drop the egg off onto a 2"x4". 2. Relevant equations I don't actually HAVE to use any equations, I just have to build the device and explain it. 3. The attempt at a solution I am still in the brain storming stage, and am just looking for helpful ideas before making a decision on what I'm going to build. I was thinking of just attaching a string to the rear axle and then to a pulley on a tower with a weight that when dropped will propel it. My main concern is taking the egg from the height of the can and lowering it, and then dropping it off on the 2"x4". Any ideas would be greatly appreciated. Thanks for taking the time to try and help.
