A 5kg mass is placed on a frictionless surface and is attached to a spring with a stiffness of

k=100N/m. The opposite end of the spring is attached to a wall. The spring is free to

compress and extend.

The mass is given an initial displacement of A = 25mm before it is released and oscillates

with simple harmonic motion between +A and -A. The period of the motion is 1s.

Determine:
