2.
A large spring requires a force of 150 N to compress it only 0.010 m. What is the spring
constant of the spring?
3.
A 0.20kg object is attached to a spring with spring constant
k
= 10 N/m and moves with
simple harmonic motion over a horizontal frictionless surface. At the instant that it is displaced
from equilibrium by

0.050 m, what is its acceleration?
4.
Tripling the weight suspended vertically from a coil spring will result in a change in the
displacement of the spring’s lower end by what factor?
5.
Tripling the displacement from equilibrium of an object in simple harmonic motion will bring
about a change in the magnitude of the object's acceleration by what factor?
a. 0.33
b. 1.0
c. 3.0
d. 9.0
