You throw a ball straight up into the air at a velocity of 15 m/s. you want to know how high above your hand the ball will be at exactly 2.5 sec after you released it.

of the 5 motion variables - vi, vf, a, δx, and t, identify which one you are solving for and the magnitudes and directions of all of the others that are known

which of the motion equations is best to use to determine the height of the ball?

how high is the ball above your hand at 2.5 sec after you throw it?

Which type of current is produced by a wire breaking magnetic field lines and changing the polarity? a. alternating b. direct c. straight d. alternating and direct

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.
