A box weighing 70 N rests on the floor. A rope tied to the box runsvertically over a pulley and a weight is hung from the other end.Determine the force that the floor exerts on the box if the weighthanging on the other side of the pulley weighs a) 30N b) 60 N andc) 90 N.
So I'm not sure where to even start with this question. Does Fnet =Faccel - Fslow apply? How do I solve this?
