My physics teacher presented us with an interesting problem, but I can't think of a resonable solution. The task is to: Move at least ten feet without the use of a motor, human propulsion or wheels. I have thought of several ways of solving this problem, but all of them would involve creating complex apparatuses. For example using a ramp and a "sled" with ice or soap on it to reduce friction, but my teacher said that their was a less elablorate way of doing it. She did say that the way she was thinking of involves soap, which I'm guessing is to reduce friction, but she hinted that it was not necesary to use a ramp, so therin lies my problem: How do you move someone ten feet without using human propultion, motors, or wheels, and with less complication then making a ramp?
