(a) Two masses m are connected by a string of length ? and constant tension T. The masses are released simultaneously. They collide and stick together. What is the mass, M, of the resulting blob?(b) Consider this scenario from the point of view of a frame moving to the left with speed v (see Figure). The energy of the resulting blob must be ?Mc2, from part (a) Show that you obtain this same result by computing the work done on the two masses.
