Conservative Forces and Potential Energy? A simple Atwood's machine uses two masses, m1 and m2. Starting from rest, the speed of the two masses is 6 m/s at the end of 5 s. At that instant, the kinetic energy of the system is 67 J and each mass has moved a distance of 15 m. Determine the values of m1 and m2
