A spring (k= 13 N/m), which can be stretched or compressed, lies flat on a frictionless table. One end of the spring is attached to the wall, and the other has a 3.8 kg mass attached. Assume the equilibrium position is labelled zero. A student pulls the mass out to x=14.0cm and releases it from rest at time t=0. The mass oscillates as a SHM.

What is the speed of the mass at time t=17 s?
