SUMMARY
The work done by the farmhand in pushing a 26-kg bale of hay across a barn floor is calculated using the formula W = F × d, where W is work, F is force, and d is distance. In this case, the farmhand exerts a horizontal force of 88N over a distance of 3.9 meters, resulting in a total work output of 343.2 Joules. The mass of the hay bale does not affect the calculation of work in this scenario, as only the force applied and the distance moved are relevant factors.
