A Certain Spring Is at Rest When Stretched 0

question 27

Multiple Choice

A certain spring is at rest when stretched 0.098 m by a 2.0 kg mass. Which function describes the motion of the mass if it is pulled down 0.25 m and released without imparting any initial velocity at time t = 0? Other helpful information: the motion is not damped; use 9.8 m s^-2 as the acceleration due to gravity; and consider the zero position to be the rest position of the spring with the mass attached, and downward motion defines the positive x direction.
