A farmhand pushes a 23kg bale of hay 4.0m across the floor of a barn.
If she exerts a horizontal force of 91N on the hay, how much work has she done?
whats the answer
To calculate the work done by the farmhand, we can use the formula:
Work = Force x Distance
Given the following values from the problem:
Force = 91N
Distance = 4.0m
Substituting the values into the formula:
Work = 91N x 4.0m
Calculating the multiplication:
Work = 364 N·m
Therefore, the farmhand has done 364 N·m of work.
To find out how much work the farmhand has done in pushing the bale of hay, we can use the formula for work done:
Work = Force × Distance
In this case, the force exerted by the farmhand is 91N, and the distance the hay is pushed is 4.0m. Plugging these values into the formula:
Work = 91N × 4.0m = 364 Joules
So, the farmhand has done a total of 364 Joules of work in pushing the bale of hay.
