A 0.54 kg mass at the end of a spring vibrates 10 times per second with an amplitude of 0.19 m.
(a) Determine the velocity when it passes the equilibrium point.
(b) Determine the velocity when it is 0.05 m from equilibrium.
(c) Determine the total energy of the system.
(d) Complete the equation describing the motion of the mass, assuming that at t = 0, x was a maximum.
