Should I use string, or elastics?

I'm trying to make a soda can roll on its own down a level hallway and someone gave me this explanation on a possible way to do it, but I'm having trouble understanding how to execute it. Can someone explain it in different words? "One complicated mechanical way is to put a flywheel inside...

Can anyone help me? This is due tomorrow and I haven't been able to get the can to move more than a meter.

Okay I've had another thought. Would it work to take the mechanism out of a wind up clock and somehow attach it to the can to make it roll? If so, how might I go about designing that?

I've thought of possibly using a gyroscope, but I'm not sure how to harness the spinning to make the can roll as well without inhibiting the gyroscope completely. Anyone know how to do that?

I've actually already tried the rubber band method. It doesn't get it to roll more than a meter or so. Is there anyway to increase the distance?

Make A Soda Can Move On Its Own I have to make some type of mechanical device to put inside an empty soda can that will make it roll on its own (I can do something to the can before setting it down like winding it up or something, but I can't push it or anything). Nothing can extend beyond 5mm...

I have to make some type of mechanical device to put inside an empty soda can that will make it roll on its own (I can do something to the can before setting it down like winding it up or something, but I can't push it or anything). Nothing can extend beyond 5mm on either side of the can and...

Homework Statement If you had a track that was in the shape of a loop-de-loop and you send a small brass ball down the track, how would you calculate how much velocity is lost due to friction? The radius of the loop is .15m. Homework Equations V = (2πr)/\sqrt{}(4(\pi^2)r)/gThe Attempt at a...

Homework Statement I had to do a lab, the diagram of which is shown. The radius (r) of the string was 50.0 cm, and our first mass was 29.0 g. The time for 20 trials was 15.75 s. We repeated the process with five other masses and recorded all the same information. Then, we had to plot the...

Homework Statement The problem is to find the minimum speed of a Formula 1 car that would produce a downforce that is greater than the force of the car. The mass of the car is given: 605kg. Homework Equations I have absolutely no idea what equations to use. The Attempt at a Solution I don't...

Thank you!

Homework Statement I have a drawing that has two masses (unequal) hanging from a string that passes over a pulley. There is an acceleration acting on each of the forces in opposite directions. Assuming that the only given information is the masses (one is M=12 kg and the other is m=6 kg) how...
