An object moves along a straight line. The position as a function of time is given by the following formula x(t) = 5 m + (2m/s) t – (0.6 m/s2)t^2.

a. Find the object’s initial position, initial velocity, and initial acceleration.
b. At what time will the object come to rest?
c. How long after starting does it take the object to pass the origin?
d. At what time is the object located at a position of +4 m from the origin?
e. Sketch the following graphs: x(t), v(t), and a(t).

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.
