OBJECTIVE 1
Frequency
Suppose that an object attached to a coiled spring is pulled down a distance of 5 inches from its rest position and then released. If the time for one oscillation is 4 seconds, write an equation that relates the displacement d of the object from its rest position after time t (in seconds). Assume no friction.
OBJECTIVE 2
d = 25 cos (4t)
OBJECTIVE 3
120.9 25
