Statement of a problem № 10885


The kinetic energy of an object attached to a horizontal ideal spring is denoted by KE and the elastic potential energy by PE. For the simple harmonic motion of this object the maximum kinetic energy and the maximum elastic potential energy during an oscillation cycle are KEmax and PEmax, respectively. In the absence of friction, air resistance, and any other nonconservative forces, which of the following equations applies to the object-spring system? A. KE + PE = constant B. KEmax = PEmax (a) A, but not B (b) B, but not A (c) A and B (d) Neither A nor B
