I need to make a mousetrap car for my physics class. I have to make it so that it can stop, but I won't know at what distance until the testing day. How should I do it?

Answer 1

make your car, then calibrate on test runs the windup needed for specified distances. Then when you are given the distance, you know exactly how much to wind it up.

Answer 2

Ok. But the mousetrap is powering the car, so it will always have the same amount of power. we are supossed to come up with a way to make the car brake at a certain distance.
