An Atwood's machine consists of a disk of radius 19 cm and mass 2.5 kg, with masses of .5 kg and .65 kg suspended from a cord over the disk. If the cord does not slip on the disk, what is the total kinetic energy of this system when the masses are moving at 25 m/s?© BrainMass Inc. brainmass.com October 10, 2019, 2:50 am ad1c9bdddf
