Name: Christopher Fuhrer If you arrived late, had to leave early, or missed the lab entirely, indicate the reason below. Supplemental Lab 2-1: Impulse, Momentum, and Collisions Due at end of class. Part 1 Impulse Equals Change in Momentum Open the simulation for the Impulse Lab Simulation (see Canvas) This simulates an astronaut (Wally) firing a fire extinguisher to propel him toward a pair of photogate timers. The simulation will keep track of how long the force was applied and the photogates and timer will allow you to calculate the speed achieved. Then we will calculate impulse and momentum to see if the Impulse equals the Change in Momentum Click on the box that says Begin Use the green arrows to Adjust the Extinguisher Force to 190 N Use the red arrows to adjust Wally’s mass to 90 kg Click Activate and watch as the astronaut accelerates toward the photogates (red lines at left). Click Shut off before 4000 ms for best results. . . . .
