Solving a problem in physics section 48 point 2 mechan

2. Body mass m1 = 0.25 kg coupled thread weightless through the block (in the form of a thin-walled hollow cylinder) with a body weight of 0.2 kg m2 = slides on the surface of the horizontal section. M = Weight of 0.15 kg. The coefficient of friction f of the body surface is equal to 0.2. Ignoring friction in the bearings, determine: 1) the acceleration a, which will move the body; 2) the tension force T1 and T2 strands on both side of the block.
