(A) Work is defined as the product of the force applied and the displacement in the direction of the force.Mathematically,$W = F 	imes s 	imes \cos(	heta)$,where $W$ is work,$F$ is force,$s$ is displacement,and $	heta$ is the angle between force and displacement.In this scenario,the person is standing still,which means the displacement $s = 0 \, m$.Since the displacement is zero,the work done $W = F 	imes 0 = 0 \, J$.Therefore,no work is done by the person.

$A$ $2 \, m$ high person is holding a $25 \, kg$ trunk on his head and is standing at a roadways bus-terminus. How much work is done by the person (in $, J$)?
