A blоck оf mаss 4.23 kg lies оn а frictionless horizontаl surface. The block is connected by a cord passing over a pulley to another block of mass 5.44 kg which hangs in the air, as shown. Assume the cord to be massless and unstretchable, and the pulley to have no friction and no rotational inertia. (a) Draw a free-body diagram for each block. (b) Calculate the acceleration (magnitude and direction) of the lighter block. (c) Calculate the tension in the cord. Note: You must write down the Newton's Second Law for each block.
