Vedclass · Answer

(A) Work done by a force is measured as the product of the magnitude of the force applied and the displacement in the direction of the force $(W = F 	imes S)$.Given:Mass of the luggage $(m)$ = $20 \, kg$Displacement $(h)$ = $1.7 \, m$Acceleration due to gravity $(g)$ = $10 \, m s^{-2}$The force applied by the porter to lift the luggage is equal to the weight of the luggage,which is $F = m 	imes g$.Therefore,the work done $(W)$ = $m 	imes g 	imes h$.$W = 20 \, kg 	imes 10 \, m s^{-2} 	imes 1.7 \, m$.$W = 340 \, J$.Thus,the work done by the porter on the luggage is $340 \, J$.

How is work done by a force measured? $A$ porter lifts a luggage of $20 \, kg$ from the ground and puts it on his head $1.7 \, m$ above the ground. Find the work done by the porter on the luggage. $(g = 10 \, m s^{-2})$
