Answer
$2889.55$ ft-lb
Work Step by Step
A package is pushed across a floor a distance of $75=S$ feet.
The force exerted on the package is $41=F$ pounds with an angle of $20^{\circ}=\theta$.
The work done is given by
\[
F \cdot S \cos \theta=\text { Work done }
\]
Substitute $F . S$ and $\theta$
\[
\begin{aligned}
&41 \cdot 75 \cos 20^{\circ}=\text { Work done } \\
&=3075 \cdot 0.94 \\
&=2889.55 \mathrm{ft}-\mathrm{lb}
\end{aligned}
\]
The work done is $2889.55$ ft-lb.
