## Homework Statement

A compound bow in archery allows the user to hold the bowstring at full draw with considerably less force than the maximum force exerted by the string. The draw force as a function of the string position x for a particular compound bow is shown in (Figure 1) .

**Part A**

How much work does the archer do on the bow in order to draw the string from x=0 to x=0.60m?

Express your answer to three significant figures and include appropriate units.

## Homework Equations

area= work

total work=sum of all areas

## The Attempt at a Solution

(.2m x 350 N)/2 + (.3m x 350 N) + (.1m x 250 N)/2 = 152.5J

153J for three sig figs.[/B]

Apparently the answer is wrong, but I do not know what I did wrong? I found the area of the two triangles, and the rectangle in the three equations above.
