A weightless and inextensible thread is thrown through a block, the mass of which can be neglected, to the ends of which loads m1 = 2.0 kg and m2 = 2.1 kg are suspended. The initial speeds of the loads are zero. What is the movement of the loads during the time τ = 3.0 s? What is the tension in the thread? With what force does the thread press on the block?
