question 444

Multiple Choice

Solve the problem by integration.
-The force $\mathrm { F }$ (in N) applied by a stamping machine in making a certain computer part is $\mathrm { F } = \frac { 3 \mathrm { x } } { \mathrm { x } ^ { 2 } + 11 \mathrm { x } + 12 }$ , where $\mathrm { x }$ is the distance (in $\mathrm { cm }$ ) through which the force acts. Find the work done by the force from $\mathrm { x } = 0$ to $\mathrm { x } = 0.6 \mathrm {~cm}$ .
