Calculating Work Done: 25lb Force at 60 Degrees on Object - Find Distance Moved

[jcamaross]

an applied force of 25lb acts on an object at an angle of 60 degrees with respect to the direction of its motion. if the work done by this force on the object is 125ft-lb,then what distance did it move while this work was done

a- 5ft
b- 10ft
c-15ft
d-20ft
e-25ft

You'll need to try to work it out and show your attempt before we can assist. What is the definition of Work?

 

[jcamaross]

I am not sure how to start it off. I know work is the total amount of energy

 

[PhanthomJay]

Work done by an applied force is total change in energy, but that doesn't help here. There is a definition of work that relates force and distance. Can you find that equation somewhere in your notes/text/reference data/on-line?
