A car of mass 2000 kg is accelerated from rest to 90 mph (equal to 40m/s) in 15 seconds. Calculate the distance traveled by the car during the 15 seconds of acceleration. (Recall that distance traveled is equal to average speed times time) I got 300m but I'm pretty sure I'm wrong, can someone confirm my answer? :')

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)
