two masses m1 = 4.70 kg and m2 which has a mass 50.0% that ofm1, are attached to a cord of negligible mass which passes over africtionless pulley also of negligible mass. If m1 and m2 startfrom rest, after they have each traveled a distance h = 2.90 m, useenergy content to determine the following.
(a) speed v of the masses
(b) magnitude of the tension T in the cord
