A small 355-g box hangs from one end of a thin light string that goes over a frictionless pulley having a moment of inertia of 0.0125 kg ? m2 and a radius of 15 cm
A second small package, this one of mass 680 g, hangs from the other end of the string. When the packages are released, the larger one accelerates downward, the lighter one accelerates upward, and the pulley turns without the string slipping. (a) What is the tension in the string on the side of the 355-g package? (b) At what rate do the packages change their speeds?
