Answer: Work done, W =311.04 J
Explanation :
It is given that,
A farmhand pushes a bale of hay 3.9 m across the floor of a barn. she exerts a force of 88 n at an angle of 25∘ below the horizontal.
We have to find the work done :
[tex]W=Fdcos\theta[/tex]
[tex]W=88\ N\times 3.9\ m\ cos(25)[/tex]
W =311.04 Joules
She has done the work of 311.04 Joules.
Hence, this is the required solution.
The work done by the farmhand will be w=311.04 Joules.
The work is defined as when force is applied on any object to displace it from its initial position to final position, then the product of the force to the displacement of the object is called as work done.
