A2.00-kg object is attached to a spring and placed on a frictionless, horizontal surface. a horizontal force of 20.0n is required to hold the object at rest when it is pulled 0.200m 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. find
(a) the force constant of the spring,
(b) the frequency of the oscillations, and
(c) the maximum speed of the object.
(d) where does this maximum speed occur?
(e) find the maximum acceleration of the object.
(f) where does the maximum acceleration occur?
(g) find the total energy of the oscillating system. find
(h) the speed and
(i) acceleration of the object when its position is equal to one-third the maximum value (of its displacement).
