A mass m2= 1.5kg rests on a horizontal table. us= .3 and uk = .25. M2 is attached by strings to m1= 2.5kg hanging over oneside of the table and m3= 4.5kg hanging over the other side. The system is initially at rest. Once released what is the acceleration of m2?(adsbygoogle = window.adsbygoogle || []).push({});

Ok for the force involving m1: m1 < m3 so m1 will be going up, so F1= T-m1g

For the force involving m3: m3 is going down so F3=m3g - T

I do not know what to do from here.

Any help would be appreciated. Thank you.

Stephen
