Question
1. An elevator with a mass of 2500Kg rest at a level 10m above the base of an elevator shaft. It is raised to 100m 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 catch arrangement to hold the elevator at the position of maximum spring compression. Assuming the entire process to be frictionless. (g-9.8 m/s²). Calculate; a) The potential energy of the elevator in its initial position b) The work done in raising the elevator c) The potential energy in its highest position d) The velocity and kinetic energy of the elevator before it strikes the spring.
