Chapter 9, Problem 28PQ

(a)

To determine

Sketch a graph of the spring force on the block $F$ versus the block’s position $x$.

(b)

To determine

The work done by the spring on the block as the block moves from the relaxed position of the spring, $x_i=0$ and $x_f=35.0\text{m}$.

(c)

To determine

The work done by the spring on the block as the block moves from the relaxed position of the spring, $x_i=0$ and $x_f=35.0\text{m}$ using the equation $W={\displaystyle {\int }_{x_i}^{x_f}{F}_x}dx$.
