Two blocks are connected by a very light string passing over a massless and frictionless pulley (the figure ). Traveling at constant speed, the 20.0- block moves 70.0 to the right and the 12.0- block moves 70.0 downward.During this process, how much work is done on the 12.0- block by gravity? During this process, how much work is done on the 12.0- block by the tension in the string? During this process, how much work is done on the 20.0- block by gravity? During this process, how much work is done on the 20.0- block by the tension in the string?
