1. The problem statement, all variables and given/known data
A meter stick rests on two counterrotating wheels. The left wheel rotates clockwise while the right wheel rotates counterclockwise. There is friction between the meterstick and each wheel. The meter stick begins offcenter to the right. What is the resulting motion of the meter stick? 3. The attempt at a solution Wouldn't the meter stick simply just not move because the two wheel velocity cancel one another? but I got it wrong. would it be The stick will be sent off the wheels to the right? because the stick was offcenter to the right at first? or would it be The stick will oscillate back and forth? or Nothing can be said about the stick's motion? or The stick will be sent off the wheels to the left? I'm quite confused

If the wheels rotated slowly the stick would be balanced between the wheels. Make the following to prove it to yourself,
