As shown in the figure below, two masses m1 = 4.40 kg and m2 which has a mass 80.0% that of m1, are attached to a cord of negligible mass which passes over a frictionless pulley also of negligible mass. If m1 and m2 start from rest, after they have each traveled a distance h = 1.00 m, use energy content to determine the following.
(a) speed v of the masses
m/s
(b) magnitude of the tension T in the cord
N
