Answer:
The work done is 202.50Nm
Step-by-step explanation:
Given
Required
The work done
First, we calculate the spring constant (k)
So:
The work done using Hooke's law is:
This gives:
Rewrite as:
Integrate
This gives:
Convert to Nm
To make this easier, first draw or imagine a vertical line at x=2
Find where the vertical line and the graph intersects.
Draw or imagine that point of intersection.
Now, draw or imagine a horizontal line that goes through the point of intersection.
That horizontal line tells us the the value of the function by passing through that mark that says "-2"
The function's value at x=2 is -2.
Have an awesome day! :)
Answer: Here ya go bro, answer is in picture below
A. Let the Initial Interest rate = x
It is given that each month Interest rate decreases by 1/4 point. Let total change of rate over the last six month= y
y = 6 x -x/4
y = -1.5x
B. Total Change
= (-1.5x-x)/(6-1)
= -2.5x/5
= -0.5x
= -5x/10
= -x/2
