A1.80-kg object is attached to a spring and placed on frictionless, horizontal surface. a horizontal force of 17.0 n is required to hold the object at rest when it is pulled 0.200 m from its equilibrium position (the origin of the x axis). the object is now released from rest from this stretched position, and it subsequently undergoes simple harmonic oscillations.
(a) find the force constant of the spring. n/m(b) find the frequency of the oscillations. hz(c) find the maximum speed of the object. m/s(d) where does this maximum speed occur? x =
