An enormous urban vehicle (euv), all 2500 kg of it, zips along the road. the driver fails to notice a stopped 1100 kg auto directly ahead. after the inevitable collision, the vehicles stick together and slide to a stop 50 m down the road. evidence technicians measure the friction coefficient to be 0.7. determine the speed the euv was going before the collision. do you think legal action is likely? explain briefly. a bug is hovering in the air (v = 0) when a heavy automobile, moving at 20 m/s, suddenly collides with it. if the collision is perfectly elastic (the bug hopes this is the case), then determine the bug's speed after the collision.

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.
