A skier is coasting at 4.0 m/s. She reaches the crest of a hill and she accelerates downhill at a rate of 0.20 m/s^2 for 10 s. How far does she travel down the hill during the 10 s?

What is the mass of the same rock on the earth

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.

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?
