The work done is 1299.03Nm
Work is done when a force acts on a body, causing that body to move a given number of meters in the same direction as the force.
The formula for work is:
[tex]W=F.dcos\theta[/tex]
We have given
[tex]F=50,d=30m,\theta=30x^{0}[/tex]
Substitute the known values in the formula , we get
[tex]W=50.30cos30\\W=1500\frac{\sqrt{3} }{2} \\W=1299.03 N.m[/tex]
Therefore the work done by the boy is 1299.03Nm.
