Question

A 3.30-kg object is attached to a spring and placed on
frictionless, horizontal surface. A horizontal force of 21.0 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* = ± m

(e) Find the maximum acceleration of the object.

m/s^{2}

(f) Where does the maximum acceleration occur?

*x* = ± m

(g) Find the total energy of the oscillating system.

J

(h) Find the speed of the object when its position is equal to
one-third of the maximum value.

m/s

(i) Find the magnitude of the acceleration of the object when its
position is equal to one-third of the maximum value.

m/s^{2}

A metal cylinder with a mass of 1.20 kg is attached to a spring
and is able to oscillate horizontally with negligible friction. The
cylinder is pulled to a distance of 0.200 mfrom its equilibrium
position, held in place with a force of 17.0 N, and then released
from rest. It then oscillates in simple harmonic motion. (The
cylinder oscillates along the x-axis, where x = 0
is the equilibrium position.)
