Arunner taking part in the 200 m dash must run around the end of a track that has a circular arc with a radius of curvature of 30 m. if he completes the 200 m dash in 23.2 s and runs at constant speed throughout the race, what is the magnitude of his centripetal acceleration as he runs the scurved portion of the track?

The assembly from prob. 3/219 is repeated here with the following additional information. the 2-kg collar at c has an outer diameter of 80 mm and is press fitted to the light 50-mm-diameter shaft. each spoke has a mass of 1.5 kg and carries a 3-kg sphere with a radius of 40 mm attached to its end. the pulley at d has a mass of 5 kg with a centroidal radius of gyration of 60 mm. if a tension t = 20 n is applied to the end of the securely wrapped cable with the assembly initially at rest, determine the initial angular acceleration of the assembly. neglect friction in the bearings at a and b and state any assumptions.

Aheat engine running backward is called a refrigerator if its purpose is to extract heat from a cold reservoir. the same engine running backward is called a heat pump if its purpose is to exhaust warm air into the hot reservoir. heat pumps are widely used for home heating. you can think of a heat pump as a refrigerator that is cooling the already cold outdoors and, with its exhaust heat qh, warming the indoors. perhaps this seems a little silly, but consider the following. electricity can be directly used to heat a home by passing an electric current through a heating coil. this is a direct, 100% conversion of work to heat. that is, 19.0 \rm kw of electric power (generated by doing work at the rate 19.0 kj/s at the power plant) produces heat energy inside the home at a rate of 19.0 kj/s. suppose that the neighbor's home has a heat pump with a coefficient of performance of 4.00, a realistic value. note: with a refrigerator, "what you get" is heat removed. but with a heat pump, "what you get" is heat delivered. so the coefficient of performance of a heat pump is k=qh/win. an average price for electricity is about 40 mj per dollar. a furnace or heat pump will run typically 200 hours per month during the winter. what does one month's heating cost in the home with a 16.0 kw electric heater? what does one month's heating cost in the home of a neighbor who uses a heat pump to provide the same amount of heating?
