A block of mass M-5 kg is attached to a spring of spring constant k-20 N/m and rests on a horizontal frictionless surface. The other end of the spring is fixed to a wall and the spring is initially relaxed. The block is given an initial velocity to the right of 7 m/s. a) What is the initial kinetic energy of the block? b) When the spring is fully compressed due to the motion of the block, what is the kinetic energy of the block? c) When the spring is fully compressed, what is the potential energy of the system? d) What is the maximum compression of the spring? e) As block undergoes a simple harmonic motion, what would be the period of the motion?
