A bear is sitting at rest on a tricycle. The bear then starts to accelerate uniformly at a rate of 2.5 m/s2. How long will it take the bear to reach a velocity of 15 m/s?

Acurve connects the data points that are plotted. (physical science chapter 11 motion)

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.
