helping nephew with paper. its english from paper, so i type exactly:

1. a particle is moved along the x-axis by a force that measures $\frac{15}{(1+x)^2}$ pounds at a point x feet from the origin. Find the work done in moving the particle from the origin to a distance of 14 feet.

i have no book.

2. $\displaystyle W=\int_{a}^{b}F(x)dx\rightarrow\int_0^{14}\frac{15 }{(1+x)^2}dx$
