Two blocks are connected by a very light string passing over a massless and frictionless pulley. Traveling at constant speed, the 20.0N block moves 75.0cm to the right and the 12.0N block moves 75.0cm downward. (use 9.8 for g).
(a) How much work is done on the 12.0N block by:
(i) gravity?
(ii) tension in the string?
(b) How much work is done on the 20.0N block by:
(i) gravity?
(ii) tension in the string?
(iii) friction?
(iv) the normal force?
