4) Two masses are connected by a string. One mass m. rests on a frictionless table, and the other mass m, is suspended from the edge of the table. The string passes over a frictionless pulley at the edge of the table (see figure 5.2 in the lab manual). a) If m, = 50 g and m, = 100 g, what is the acceleration of the masses immediately after they are released from rest? b) If 15 g is transferred from m, to m,, such that m, = 65 g and m, = 85 g what is the acceleration of the masses immediately after they are released from rest
