Assume a rope of non-negligible mass M, pulls a block of mass M, with a non-zero acceleration on a horizontal frictionless plane. a) Show that if M, < < M,, the tension at each end of the rope is equal. b) Argue using Newton's Third Law that the tension throughout the rope is uniform. Or mo m m2 In the arrangement shown above, the bodies have masses mo, m, and m, friction is absent and the masses of the pulleys and threads are negligible. Show that the magnitude of the acceleration of m, equals (4m,m+m,(m-m))g (4m,m,+m(m+m))
