Impulse With Prediction Lab
In this lab you will be able to control the amount of time the astronaut will be firing the extinguisher. Your job is to see how the amount of time of fire affects the momentum they obtain. You calculate momentum by multiplying mass of the astronaut by their speed going through the gates.
Once you have discovered this relationship, you will then use it to make predictions on things you didn't actually measure.
When you are ready to start the experiment, click on the begin button.

Begin
Give momentum to your astronaut by hitting 'Activate' and creating thrust from the fire extinguisher.Next, hit 'Stop' to end the force after an arbitrary amount of time has passed.Then determine the speed and momentum created by the impulse by timing the astronaut's travel through the photogates.
Finished
Create a graph with momentum (kg*m/s) obtained by the astronaut on the y-axis and the time of fire on the x-axis.Enter the slope below and then use the equation you discovered to find the speed created if the astronaut fired the extinguisher for x seconds.Finally, find the thrust of the fire extinguisher by multiplying the slope of your graph by the mass of the astronaut.
