A 0.5 kg glider, attached to the end of the ideal spring with force constant k=450 N/m, undergoes SHM with amplitude of 0.04 m. Compute:
1) The maximum speed of the glider;
2) The total mechanical energy of the glider
3) The speed of the glider when it is at x = -0.015m;
4) The magnitude of the maximum acceleration of the glider;
