A bumping post at the end of a track in a railway

A bumping post at the end of a track in a railway yard has a spring constant k 8.0 MN/m (see figure). The maximum possible displacement d of the end of the striking plate is 450 mm.

What is the maximum velocity vmax that a railway car of weight W = 545 kN can have without damaging the bumping post when it strikes it?
