A very light string going on a massless and frictionless pulley, is connecting two blocks. The two blocks are traveling at constant speed, the m = 2.0 Kg travelled 50cm and m₂=1.0 moved 45 cm down. (a) How much work is done on the 1.0 kg block by (i) gravity and (ii) the tension in the string? (b) How much work is done on the 2.0 kg block by (i) gravity, (ii) the tension in the string, (iii) friction, and (iv) the normal force? M₁ my
