The pictured system below consisting of the masses m, and m2, the massless cable and the massless pulleys is released at time t = 0. One of the pulleys is fixed in A. The motion of the cable over the pulleys occurs without friction. The cables do not stretch. The system moves under the influence of gravity.

The pictured system below consisting of the masses m, and m2, the massless cable and the massless
pulleys is released at time t = 0. One of the pulleys is fixed in A. The motion of the cable over the pulleys
occurs without friction. The cables do not stretch. The system moves under the influence of gravity.
Given:
m1 ; m2 ; m1 >;m2; g
Find:
Using both Newton's and d'Alembert's laws, determine,
1. the positions x,(t) and x2(t) of the masses m, and m2
2. the cable force S(t).
