A very light string going on a massless and
frictionless pulley, is connecting two blocks. The
two blocks are traveling at constant speed, the mi
= 2.0 Kg travelled 50cm and m₂=1.0 Kg 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?
(c) Find the total work done on each block..
