In this lab you will use your fire extinguisher to do different amounts of work to astronaut Wally. For each trial you are to determine Wally's speed as he passes between the two photogates that are 10 meters apart. You can control the mass of Wally, the strength of the force from the fire extinguisher, and the distance over which the force of the extinguisher is applied.

You must turn off the extinguisher before he reaches the first photogate. When you are ready to start the experiment, click on the begin button.
