A 0.35-kg mass at the end of the vibrates 3 times per second with an amplitude of 0.15m. Determine (a)the velocity when it passes the equilibrum point (b)the velocity when it is 0.10m from the equilibrum point(c)the total energy of the system(d)the equation describing the moiton of the mass assuming that at t=0, x was maximum

ok i know that v=sqrtk/m(A^2-x^2)

the velocity would be V=sqrtk/m(0.15^2-0)

V=sqrtk/0.35(0.15^2-0)---other than that im am stuck can someone help

Thnx
