Solution to the Half-Atwood Machine. The tension in the string depends on the weight of mass 2 as well as the acceleration of mass 2. However, ...

Note that the problem is the same as for this single Atwood's Machine: Apply Newton’s second law to the three objects assuming that the acceleration of the $2m$ mass is equal in magnitude and opposite ...

Bartenders up and down the Northeast corridor are trotting out their fall drinks — boozy concoctions of whiskey and dark rum, solemn and carefully constructed. These are the Kurosawas or ...

In Lesson 11 part 2, students continue to explore forces. Students use evidence (SEP.3) gathered in the Atwood machine investigation in part 1 to explain how the strength and direction of a force ...
