$\"\"$

Values of a force function $\"\"$ are shown in the table.

Where $\"\"$ is measured in meters and $\"\"$ in newtons.

Determine the work done by the force in moving an object from $\"\"$ to $\"\"$ using mid point rule.

Consider the number of subintervals as $\"\"$ .

Width of the interval $\"\"$ .

Mid points are $\"\"$ and $\"\"$ .

Mid point Rule :

Work done by the force is $\"\"$ .

Substitute $\"\"$ and corresponding values from the table in above expression.

$\"\"$

$\"\"$ J.

Work done by the force is $\"\"$ J.

$\"\"$

Work done by the force is $\"\"$ J.
