Two blocks are connected by a very light string passing over a massless and frictionless pulley. The 20.0-N block moves 75.0 cm to the right and the 12.0-N block moves 75.0 cm downward.
a) Find the total work done on 20.0-N block if ?s=0.500 and ?k=0.325 between the table and the 20.0-N block
b) Find the total work done on 12.0-N block if ?s=0.500 and ?k=0.325 between the table and the 20.0-N block.
