Bicycle Problem
An ordinary bicycle is supported lightly so that it rests on its wheels. It will move forwards or backwards and will not fall over.. It rests on a level road with the pedal cranks vertical. A piece or rope is secured to the lower pedal and is led to the rear of the bicycle with the rope parallel to the road. A steady pull is exerted on the rope.
Which way does the bicycle move?
..forward or backward??? heheh
