Three objects each have mass m. Each object feels a force from the other two, but not from any other object. Initially the first object is at x=−L, y=0; the second object is at x=+L, y=0; and the third object is at x=0, y=L. The momentum of the system of the particles at the initial time is zero. At a later time the first object is at x=−L/3, y=+L/4; and the second object is at x=+L/2, y=−L. At this later time, where is the third object? Find the x-position of the third object.

Steam is generated in a boiler of a cogeneration plant at 10 mpa and 450°c at a steady rate of 5 kg/s. in normal operation, steam expands in a turbine to a pressure of 0.5 mpa and is then routed to the process heater, where it supplies the process heat. steam leaves the process heater as a saturated liquid and is pumped to the boiler pressure. in this mode, no steam passes through a condenser, which operates at 20 kpa. (a) determine the power produced in the turbine and the rate at which process heat is supplied in this mode. (b) determine the power produced in the turbine and the rate of process heat supplied if only 60 percent of the steam is routed to the process heater and the remainder is expanded to the condenser pressure.
