Problem 1
An ideal Atwood machine has masses and hanging on opposite sides of a light inextensible string over a frictionless, massless pulley; take as the gravitational acceleration and assume the system is released from rest. The heavier mass moves downward, with both masses having the same acceleration magnitude because the string length is fixed. (a) Find the acceleration. (b) Find the string tension. (c) Find the speed after the heavier mass has descended a distance .

Substituting the result into the relevant definition or law gives the next quantity. This connects the parts of the problem instead of treating their answers separately.
