Blocks of mass m1 and m2 are connected by a light string over a pulley, as shown. A) Find an expression for the acceleration of block m2 if the pulley is massless and frictionless, and the surface is frictionless. B) repeat part a for the case where the surface has coefficient of friction µ and the pulley is a frictionless disk with mass M and radius R. (can you answer both a and b, thank you)
