Three balls are thrown off a tall building with the same speed but in different directions. ball a is thrown in the horizontal direction; ball b starts out at 45° above the horizontal; ball c begins its flight at 45° below the horizontal. which ball has the greatest speed just before it hits the ground? assume that the ground near the building is level, and ignore any effects due to air resistance.

Arefrigerator uses r-134a as the working fluid and operates on the ideal vapor-compression refrigeration cycle except for the compression process. the refrigerant enters the evaporator at 120 kpa with a quality of 34 percent and leaves the compressor at 70°c. if the compressor consumes 450 w of power, determine (a) the mass flow rate of the refrigerant, (b) the condenser pressure, and (c) the cop of the refrigerator.
