The 150-g hockey puck initially rests on a surface at A with the spring compressed by 0.2 m, as shown. The kinetic friction coefficient between the surface and the puck is ?? = 0.1. The puck is in contact with the spring but is not attached to it. Subsequently, the spring is released. Determine the minimum stiffness of the spring so that the puck just clears the wall at B. Use any method(s) that you like
