Question

a student builds a mousetrap car for distance. to maximize the distance, they should use a long lever arm. why? a long lever arm decreases the mechanical advantage a long lever arm adds more potential energy to the system a long lever arm allows the springs energy to be released more slowly a long lever arm increases the force exerted n the axle

Explanation:

The potential energy stored in the mousetrap spring - lever system is related to the amount of work done to set it. A longer lever arm allows for more work to be done in setting the mousetrap, thus adding more potential energy. This potential energy is then converted to kinetic energy to move the car, and more potential energy can lead to greater distance traveled.

Answer:

A long lever arm adds more potential energy to the system
