## Homework Statement

Two masses A and B, and of mass 1.6kg and 2.4kg respectively are connected by a light string which passes over a frictionless pulley. Calculate the acceleration of the 1.6kg mass.

## Homework Equations

## The Attempt at a Solution

To get started I must know whether the two masses both have the same acceleration. Is that true? I know the tension of the system is the same.

Assuming it's true I get a simultaneous equation that looks like

16-T=1.6a

24-T=2.4a

which works out for a=10m/s^2 and T=0 which is a bit fishy. But if a is different for each mass than there are 3 variables but only two equations.
