Molly the ant falls from a height h above a conveyor belt which is moving at a constant, very high, velocity Vc, and she bounces off at an angle
9 to the horizontal. Molly has a mass m and the coefficient of kinetic friction
between Molly and the belt is u. Draw a diagram showing all the forces
acting on Molly during her collision with the conveyor belt. Indicate on your
diagram the relative sizes of the forces in the vertical direction.​
please help

Crowbar of 5 metre is used to lift an object of 800 metre if the effort arm is 200cm calculate the force applied

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.
