(1 diggs) An easy way to boost women's scores in physics. - By Amanda Schaffer - Slate Magazine
Two 15-minute writing exercises, administered to an intro physics class early in the semester, could substantially boost the scores of female students. Even more curious: the exercises had nothing to do with physics. Instead, students were asked to write about things that mattered to them, like creativity or relationships with family and friends. How could a few paragraphs on personal values translate into enduring better mastery of pulleys and frictionless planes?

In this problem a mass on a frictionless table is connected by massless ropes over ideal pulleys at opposite ends of a table. The acceleration of the system and the tensions in each of the ropes is expressed in terms of m1, m2, m3, and g. The limiting cases of a Very Large m1, a Very Large m3, and a very small m2 are considered.
