Question :

A simple Atwoods machine uses a massless pulley and two masses m1 and m2. Starting from rest, the speed of the two masses is 4.2 m/s at the end of 4.7 s. At that time, the kinetic energy of the system is 94 J and each mass has moved a distance of 9.87 m. 9.87 m Find the value of heavier mass. The accel- eration due to gravity is 9.81 m/s2 . Answer in units of kg 002 (part 2 of 2) 10.0 points Find the value of lighter mass. Answer in units of kg
