Two massless springs with spring constants k1=4.0N/m and k2 = 6.0 N/m are welded together at point A. A mass m = 1.0 kg that slides along the frictionless surface is incident on the springs with a velocity of V0 = .5 m/s. It hits a massless plate with velcro on the end of spring 2 and sticks.
a) In terms of k1 and k2 what is the effective spring constant keff characterizing the system, i.e. what is the spring constant of the single spring that could replace these two and give the same motion of the mass?
b)What is the maximum compression Xmax that the mass reaches from the initial equilibrium length of the springs?
The diagram has the mass sliding towards the springs where it would hit spring 2 which is joined to spring 1 at point A, with spring 1 attached to the wall.
