Two blocks with mass M1 and M2 are arranged as shown with M sitting on an inclined plane
Two blocks with mass M1 and M2 are arranged as shown with M sitting on an inclined plane and connected with a massless unstretchable string running over a massless, frictionless pulley to M2, which is hanging over the ground. The two masses are released initially from rest. The inclined plane has coefficients of static and kinetic friction μs and μk respectively where the angle θ is small enough that mass M1 , would remain at rest due to static friction if...
