Aweight lifter lifts a set of weights a vertical distance of 3.85 m. if a constant net force of 350 n is exerted on the weights, what is the net work done on the weights? (show all work and include units of measure)

work done is defined as product of force and displacement in the direction of force.

So we can say formula of work done is

so here it is given that

F = 350 N

d = 3.85 m

from above equation we have

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
