As shown in figure, find that at what distance body A will attain a velocity of 3 m/s when starts from rest. 

Find the acceleration of the three weights shown in fig. Assume pulleys are frictionless. Also, find the tension in the cables. 

A frictionless piston-cylinder device contains 8 kg of superheated water vapor at 500 kPa and 300oC. Steam is now cooled at constant pressure until 70 percent of it, by mass condenses. Determine the work done and heat transfer during this process.
