Textbook Question
Chapter 6, Problem 36PCE
Predict/Explain Suppose m1 and m2 in Example 6-14 (Atwood’s Machine) are both increased by 1 kg. Does the acceleration of the blocks increase, decrease, or stay the same? (b) Choose the best explanation from among the following:
- I. The net force acting on the blocks is the same but the total mass that must be accelerated is greater.
- II. The difference in the masses is the same, and this is what determines the net force on the system.
- III. The force exerted on each block is greater, leading to an increased acceleration.
