Question description

Help me understand this problem:A mass M is attached to a spring which has unstretched length L and spring constant k, and the spring has mass m which is uniformly distributed along the spring. The free end of the spring is attached to a horizontal frictionless surface and the mass is free to move along the direction of the spring.(a) Consider a short element of the spring of length dx at a distance r from the fixed end of the spring. When the mass M is moving with velocity v, what is the kinetic energy of this spring element? (b) What is the total kinetic energy of the spring at the moment when the mass M is moving with velocity v? Integrate your expression in part (a). (c) Does this system exhibit simple harmonic motion? If so, what is its frequency?
