A car travelling 30 m/s [E] attempts to pass a truck that is 25 m in front of it travelling 35 m/s [E] by accelerating at 3.5 m/s/s [E]. However, the truck has
other ideas and decides to accelerate uniformly at 1.5 m/s/s [E]. How long AND
how far does it take for the car to pass the truck?

Acommercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at -35°c by rejecting waste heat to cooling water that enters the condenser at 18°c at a rate of 0.25 kg/s and leaves at 26°c. the refrigerant enters the condenser at 1.2 mpa and 50°c. if the compressor consumes 3.3 kw of power, determine (a) the mass flow rate of the refrigerant, (b) the refrigeration load, (c) the cop, and (d) the minimum power input to the compressor for the same refrigeration load.
