- 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. Part (d) Imagine that the N springs from part (c) are released from rest simultaneously. If the potential energy stored in the springs is fully converted to kinetic energy and thereby "released" when the attached…As shown in the figure, a 1.50 kg box is held at rest against a spring with a force constant k = 725 N/m that is compressed a distance d. When the box is released, it slides across a surface that is frictionless, except for a rough patch that has a coefficient of kinetic friction μk = 0.47 and is 6.0 cm in length. (a) Calculate the spring's potential energy in terms of d d2 (b) Calculate the magnitude of the friction force (in N). N (c) Calculate the work done by the frictional force (in J). Be sure to include the correct sign in your answer. J (d) The speed of the box is 1.9 m/s after sliding across the rough patch. Calculate the initial compression d (in cm) of the spring. cmA block of mass m = 1.9 kg is attached to a spring of force constant 500 N/m. The assembly lies on a horizontal frictionless surface. The block is pulled 7.0 cm to the right of equilibrium. What was the work required to stretch the spring?
