Answer
The work done is 7600 foot-pounds.
Work Step by Step
Here, the car is being pushed along the level road. Hence, the angle between force and direction of motion is ${{0}^{\circ }}$.
Now it is known,
$\mathbf{W}=\left\| \mathbf{F} \right\|\left\| \mathbf{AB} \right\|\cos \theta $ …… (1)
As it is given that,
$\left\| \mathbf{F} \right\|=95,\left\| \mathbf{AB} \right\|=80$ and $\theta =0{}^\circ $ …… (2)
Therefore, use (2) in (1).
So,
$\begin{align}
& \mathbf{W}=\left( 95 \right)\left( 80 \right)\cos \left( 0{}^\circ \right) \\
& =7600
\end{align}$
