QUESTION:
A wooden plank rests on two soup cans laid on their sides. Each can has a diameter of 6.5 cm, and the plank is 3.0 m long. Initially, one can is placed 1.0 m inward from either end of the plank, as Figure 10–29 shows. The plank is now pulled 1.0 m to the right, and the cans roll without slipping. (a) How far does the center of each can move? (b) How many rotations does each can make?
ANSWER:
Step 1 of 2
Part a
We are required to calculate the distance moved by center of each can.
Total distance moved by the plank is 1.0 m.
Therefore, the center of each can moves by 1.0/2 m = 0.5 m.
