Therefore, the work done by the force is 2500 foot-pounds.
Work Done:
When an object moves while a force is being exerted on it, then work is being done on the object by the force.
If an object moves through a displacement d while a constant force F is acting on it, the force does an amount of work equal to,
[tex]W=F \cdot d\\F=Fd cos\phi[/tex]
Where [tex]\phi[/tex] is the angle between [tex]d\ and\ F[/tex].
Given that,
[tex]F=50\ pounds, \\d=100\ feet, \\\phi=60[/tex]
So, Work done is,
[tex]Work\ done=50\times 100\times cos60\\=2500 \ foot\ pound[/tex]
