2. [-/1 Points] A spring has a spring constant value of 3300N/m. Determine the work needed to stretch the end of the spring, at a constant velocity, from x=3.6 cm to x=4.6 cm, where x=0 is the position of the spring at equilibrium (position where the spring is neither stretched or compressed), Helpful algebra reminder. a^2-b^2+(a-b)^2 square MY NOTES ASK YOUR TEACHER

To determine the work needed to stretch the end of the spring from
cm to
cm, we can use the formula for the work done on a spring:
where:-
is the work done,-
is the spring constant,-
and
are the initial and final positions of the spring, respectively.Given:-
-
-
Now, plug these values into the formula:
First, calculate
and
:
Next, find the difference:
Now, multiply by the spring constant and
:
Therefore, the work needed to stretch the end of the spring from
cm to
cm is
joules.
