Cho places a letter from Cedric in a box and pushes the now 1.5 kg box against a 25 N/m spring and compresses it leftwards 0.5 m pver a rough patch of scarring on the table with a coefficient of friction of 0.2. She then releases the box so it slides against the table for 2.30 until it launches off at 75 degrees, to the horizontal. It lands in a pile of boxes 3.5 m away from the base of the table. fi the box can withstand a maximum fall from 2,5 m high, will the box land safely or will her letter be ruined?

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.

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.
