Problem
Two unequal masses m1 and m2 (m2>m1) are connected by a light string over an ideal pulley and released from rest.
(i) Obtain an expression for the acceleration of the system.
(ii) Examine your expression to determine the value that the acceleration approaches as m2 becomes much larger than m1. Explain your reasoning.
(iii) Under what physical circumstance would the acceleration actually be equal to g? Give a brief explanation.
