Chapter 10 Elasticity and Oscillations 44. A mass is suspended vertically from a spring so it is at rest at the equilibrium position. The mass is pulled straight down to an extension x and released so that it oscillates about the equilibrium position. The speed of the mass is greatest when: A. the mass is at its maximum upward travel. B. the mass is at the equilibrium point. C. the mass is at its maximum lower travel. D. the mass is somewhere between the equilibrium point and maximum extension. 45. A mass is suspended vertically from a spring so it is at rest at the equilibrium position. The mass is pulled straight down to an extension x and released so that it oscillates about the equilibrium position. The acceleration of the mass is zero when:
