1. The problem statement, all variables and given/known data A Modified Atwood's Machine has a 10 N cart on a frictionless, horizontal track with a 10 N hanging weight attached to a string connecting the two weights. A second track is set up with the hanging weight replaced by a person who can maintain a 10 N pull on the string (as measured with a force probe). Which set-up has the greater acceleration? 2. Relevant equations N/A 3. The attempt at a solution Wouldn't they have equal acceleration since the force pulling them is the same?
