Kyle, a 95.0 kg 95.0 kg football player, leaps straight up into the air (with no horizontal velocity) to catch a pass. He catches the 0.430 kg 0.430 kg ball precisely at the peak of his jump, when he is 0.488 meters 0.488 meters off the ground. He hits the ground 0.0333 meters 0.0333 meters away from where he leapt. If the ball was moving horizontally when it was caught, how fast was the ball traveling?

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.
