Abaseball pitcher brings his arm forward during a pitch, rotating the forearm about the elbow. if the velocity of the ball in the pitcher's hand is 37.137.1 m/s (about 8383 mph) and the ball is 0.3300.330 m from the elbow joint, what is the angular velocity of the forearm?

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. (0.00644 kg/s, 800 kpa, 2.03)
