Question

An 18.5 lb box is placed on the ground.

What force (in lb) does the ground exert on the box? (magnitude and direction).
A cord is attached to the box and run through a pulley directly above the box, so that the cord is vertical. The free end of the cord is then connected to a hanging weight. Calculate the force exerted by the ground on the box (in lb), if the hanging weight is 12.0 lb (magnitude and direction)
A 29.0 lb weight is substituted for the 12.0 lb weight. Calculate the new force (in lb) exerted by the floor on the box (magnitude and direction).
