1. In this momentum experiment, why should you shut off the fire extinguisher before Wally reaches the first photogate red line? Which of Newton's three laws of motion are in effect here?

2. What is the fire extinguisher propulsion effort doing to Wally's body mass each second it is spraying?

3. How many different methods of calculation can you use to determine the speed of Wally?

4. When is Wally's speed changing, during the spraying of the fire extinguisher or when the fire extinguisher is off? Which of Newton's three laws of motion are applicable here?
