In the arrangement shown in Fig. 1.16 the bodies have masses mo, m1 , m2 ,the friction is absent, the masses of the pulleys and the threads are negligible. Find the acceleration of the body m1. Look into possible cases.
Let us write Newton'* second law for masses m1 and m2 and moving pully in the vertical direction along the positive x-axis (Fig.):
Simultaneous solution of the obtained five equation yields:
