An Atwood machine (two masses connected via a cord that passes over a massless pulley) is set up with a 340-gram weight on one side and a 230-gram weight on the other.

Both masses start from rest, and when released the 340-gram weight falls through a distance of 0.50 m while pulling the other weight up by the same amount.

What is the average power output of the 340-gram weight on the 230-gram weight?

A

$0.525 W$

B

$1.05 W$

C

$1.31 W$

D

$2.62 W$

E

None of the above
