What will be the shape of speed of sound in air versus pressure at constant temperature ?

A block of mass m lies on a horizontal frictionless surface and is attached to one end of a horizontal spring (with spring constant k ) whose other end is fixed . The block is intinally at rest at the position where the spring is unstretched (x=0) . When a constant horizontal force vec(F) in the positive direction of the x- axis is applied to it, a plot of the resulting kinetic energy of the block versus its position x is shown in figure. What is the magnitude of vec(F) ?
