work done is defined as product of force and displacement in the direction of force.
So we can say formula of work done is
[tex]W = F.d[/tex]
so here it is given that
F = 350 N
d = 3.85 m
from above equation we have
[tex]W = 350 * 3.85[/tex]
[tex]W = 1347.5 J[/tex]
So net work done is 1347.5 J
Here this is net work done which includes Work done by applied force and also the work done by gravitational force of earth
