Part 1 Impulse Equals Change in Momentum Open the simulation for the Impulse Lab Simulation (see Canvas) https://www.thephysicsaviary.com/Physics/Programs/Labs/ImpulseLab/ 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. After shutting the force down, he will coast at a constant speed until he triggers the timer at the first photogate and shuts the timer off at the second photogate. [Be sure to shut off the force well before he reaches the red lines.] Note that the time units are ms which stands for milliseconds. There are 1000 milliseconds in 1 second. The photogates are 10.000 meters apart. Record the results next: Photogate Time = 1160 ms Force Time = 4070 ms Convert the times in milliseconds to seconds by dividing each time by 1000. Record the times in standard units below. Photogate Time = 1.16 s Force Time = 4.07 s Calculate his velocity using the formula v=d/s
