A boy pulls with a 92.5 N force on the handle of a 27.5 kg wagon while the handle makes an angle of 35.0 degrees with the horizontal. If friction is negligible, and the boy pulls a total distance of 215.6 m, how much work has the boy done

Answer:

[tex]W_b \approx 16336J[/tex]

Explanation:

From the question we are told that

Force of pull [tex]F= 92.5[/tex]

Weight of handle [tex]W_h=27.5 kg[/tex]

Angle of handle [tex]\angle =35.0[/tex]

Distance [tex]d=215.6 m[/tex]

Generally the work done by the boy can mathematically be represented as

[tex]W_b=F*dcos \theta[/tex]

[tex]W_b=92.5*27.5 *cos(35)[/tex]

Therefore

[tex]W_b=16336.34922J[/tex]

[tex]W_b \approx 16336J[/tex]
