An elevator with a mass 2500 kg rests at a level 10 m above the base of an elevator shaft. It is raised to 100 m above the base of the shaft, where the cable holding it breaks. The elevator falls freely to the base of the shaft and strikes a strong spring. The spring is designed to bring the elevator to rest and, by means of a catch arrangement, to hold the elevator at the position of maximum spring compression. Assuming the entire process to be frictionless & and taking g = 9.8 m/s? . The potential energy in J of the elevator in its initial position relative to the base of the shaft 245.000 O 367,500 612,500 490,000
