EXPLANATION
The velocity equation of the oscillating spring is given by the function.

To find the displacement function, we need to to Integrate the velocity function.


At time t=0, there was no displacement.
This implies that,




The displacement function then becomes,

To find the displacement over the first π seconds, we put

into the equation for the displacement to get,



Answer:
x4+2x3+x2+5x+b=x-2x3+x+3
Step-by-step explanation:
<span>Unary minus: -8
</span><span>Multiple: 5 * (-8) = -40
</span><span>Multiple: 14 * (-40) = -560
The answer is -560
