SPREADSHEET Ablock of wood (mass m) is connected to two
Chapter , Problem 108(choose chapter or problem)
SPREADSHEET Ablock of wood (mass m) is connected to two massless springs, as shown in Figure 7-59. Each spring has unstressed length L and force constant k. (a) If the block is displaced a distance x, as shown, what is the change in the potential energy stored in the springs? (b) What is the magnitude of the force pulling the block back toward the equilibrium position? (c) Using a spreadsheet program or graphing calculator, make a graph of the potens tial energy U as a function of x for Assume and (d) If the block is displaced a distance and released, what is its speed as it passes through the equilibrium point? Assume that the block is resting on a frictionless surface.
