7. A mass-spring system consists of a mass of 2 kg and the spring has a length of 0.9 m. A force of 25.6 Newtons is needed to maintain the spring stretched to a length of 1.1 m. Assume the spring is stretched to a length of 1.1 m. and then it is released with some initial velocity of "0". The task is to find the position of the mass at any time.
