A massless spring of spring constant k = 4307 N/m is connected to a mass m = 105 kg at rest on a horizontal, frictionless surface. Part (a) The mass is displaced from equilibrium by A = 0.81 m along the spring's axis. How much potential energy, in joules, is stored in the spring as a result? Part (b) When the mass is released from rest at the displacement A= 0.81 m, how much time, in seconds, is required for it to reach its maximum kinetic energy for the first time? Part (c) The typical amount of energy released when burning one barrel of crude oil is called the barrel of oil equivalent (BOE) and is equal to 1 BOE = 6.1178362 GJ. Calculate the number, N, of springs with spring constant k = 4307 N/m displaced to A = 0.81 m you would need to store 1 BOE of potential energy.
