A weight 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)

Respuesta :

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
