A wooden plank rests on 2 soup cans laid on their sides. Each can has a diameter of 6.5 centimeter, and the plank is 3.0 meter long. Initially, one can is located 1.0 meter inward from either end of the plank. The plank is now pulled 1.0 meter to the right, and the cans roll without slipping.
a) Compute how far does the center of each can move?
b) Determine how many rotations does each can make?
