Given that work is the vectorial product of displacement and force. Work can be found with the formula W=F·d
The force that does work as the weight is lifted is gravity. The force is weight
Hence
F
=F[tex]_{gravity}[/tex]
= weight
= mass(acceleration due to gravity)
= 32 pounds(9.8 m/s²)
=14.51(9.8) N
= 142.198
With the F= 142.2, d=10 ft = 3.04 m
W=F·d
= 142.2· 3.04
= 432.228 J (Joules)
432.228 joules of work was done
