Answer:
2.56 N/m
Step-by-step explanation:
The force exerted by a spring is given by the equation:

where
is the spring constant, and
is the distance that the spring is stretched or compressed from its equilibrium.
To find
, we will simply subtract the spring's initial position from its final position:

It is given in the problem that the force exerted by the spring is 3.20 Newtons. So, we can solve the equation for
and calculate the spring constant.
