13.84: a) As the mass approaches the origin, the motion is that of a mass attached to a spring of spring constant k , and the time to reach the origin is . 2 k m π After passing through the origin, the motion is that of a mass attached to a spring of spring constant 2 k and the time it takes to reach the other extreme of the motions is . 2 2 k m π

Unformatted text preview: The period is twice the sum of these times, or ( 29 2 1 1 + = k m T . The period does not depend on the amplitude, but the motion is not simple harmonic. B) From conservation of energy, if the negative extreme is ; so , ) 2 ( , 2 2 2 1 2 2 1 A A A k kA A-= = the motion is not symmetric about the origin....
