- Homework Statement
- An air track car A collides with a stationary air track car B (you may assume that the surface is frictionless). Two photogate timers are used to obtain data that allowed to determine the momentum of the system of cars before and after the collision. After the collision, the final velocities of the cars are in opposite directions. If the total momentum after the collision (0.3869 kg m/s) is greater than the total momentum before the collision (0.3782 kg m/s), what is the largest cause for a gain in momentum during the collision?

- Relevant Equations
- $$p = mv $$

I've come up with the following causes:

- air resistance

- parallax

- during the collision, some of the kinetic energy gets converted into thermal energy.

- invisible deformations

But I'm not sure which would be the biggest effect on the total momentum change.

Are there any other reasons that could have changed the total momentum?
