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) Choosethe best explanation from among the following:I. The net force acting on the blocks is the same, but the totalmass 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.

Question

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.
