Astuntman drives a car with a mass of 1500 kg on a drawbridge. the car accelerates with a constant force of 10,000 n. while he is driving, the drawbridge is raised to an incline of 30°. what is the car's new acceleration on this incline, ignoring the force due to air resistance? (recall that g=9.8 m/s^2)

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.
