Statement-1: Graph between potential energy of spring versus the extension or comparision of the spring is a straight line. Statement-2: Potential energy of a stretched or compressed spring is proportional to square of extension or comparission.

A block of mass m is initially moving to the right on a horizontal frictionless surface at a speed v. It then compresses a spring of spring constant k. At the instant when the kinetic energy of the block is equal to the potential energy of the spring, the spring is compressed a distance of :
