A mass m oscillates with simple harmonic motion with frequency $f = \frac{\omega }{{2\pi }}$ and amplitude A on a spring with constant $K$ , therefore

  • A

    The total energy of the system is $\frac{1}{2}K{A^2}$

  • B

    The frequency is $\frac{1}{{2\pi }}\sqrt {\frac{K}{M}} $

  • C

    The maximum velocity occurs, when $x = 0$

  • D

    All the above are correct
