A mass-spring system moves with simple harmonic motion along the x axis between turning points at x 1 = 19 cm and x2 = 88 cm. (1) At which position does the particle have the greatest magnitude of momentum? 19 cm 44 cm 53.5 cm some other position The greatest value occurs at multiple points. (II) At which position does the particle have greatest kinetic energy? 19 cm 44 cm 53.5 cm some other position
