An atwood machine consists of two masses, ma = 6.8 kg and mb = 8.0 kg , connected by a cord that passes over a pulley free to rotate about a fixed axis. the pulley is a solid cylinder of radius r0 = 0.40 m and mass 0.80 kg .1. determine the magnitude of the acceleration a of each mass.
2. what percentage of error in a would be made if the moment of inertia of the pulley were ignored? ignore friction in the pulley bearings.

Acommercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at -35°c by rejecting waste heat to cooling water that enters the condenser at 18°c at a rate of 0.25 kg/s and leaves at 26°c. the refrigerant enters the condenser at 1.2 mpa and 50°c. if the compressor consumes 3.3 kw of power, determine (a) the mass flow rate of the refrigerant, (b) the refrigeration load, (c) the cop, and (d) the minimum power input to the compressor for the same refrigeration load.
