A 2000 kg elevator with broken cables in a test rig is falling at 4.0 m/s when itcontacts a cushioning spring at the bottom of the shaft. The spring is intendedto stop the elevator, compressing 2.0 m as it does so. During the motion asafety clamp applies a constant 17,000 N frictional force to the elevator. Whatis the necessary spring constant, k

The magnitude of the amount of energy released by burning a fuel source, measured in energy per unit mass, is called its fuel value. note that the fuel value is the negative of the isobaric specific heat of combustion for the fuel. if all the energy obtained from burning 1.23 pounds of butane with a fuel value of 10.85 kcal/g is used to heat 128.0 kg of water at an initial temperature of 18.3 °c, what is the final temperature? note that 1 lb = 453.6 g.
