I thought I had included this in the original email but apparently I didn't. We pulled the wagon 3 meters.
By the way, be careful in your calculations. If you use v=d/t that gives you the average velocity. To calculate, acceleration, you need the velocity the person was going at the end of the 3 meters. This is something we've had quiz questions on and we've done in one of the ramp and ball labs we did a while ago. I'll leave you with that. Feel free to email me if you need hints.
Good luck everyone!
