31. if a simple machine provides an increased output force, what happens to the output distance? (2 points)

Can someone explain to me how to do this problem ?

Rank the automobiles based on the magnitude of the force needed to stop them, from largest to smallest.2000 kg car going 5m/s500 kg car going 20 m/s1000 kg car going20m/s500 kg car going10m/s1000 kg car going10/s4000 kg car going 5m/s 0 0 603

In a series circuit the __ is the same at every point
