Question

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 1

`W_b \approx 16336J`

Step-by-step explanation:

From the question we are told that

Force of pull
`F= 92.5`

Weight of handle
`W_h=27.5 kg`

Angle of handle
`\angle =35.0`

Distance
`d=215.6 m`

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

`W_b=F*dcos \theta`

`W_b=92.5*27.5 *cos(35)`

Therefore

`W_b=16336.34922J`

`W_b \approx 16336J`
