(a) what force (in lb) does the ground exert on the box? magnitude i lb direction i --$elect-- v i (b) 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 lo), if the hanging weight is 12.0 lo. magnitude | lb direction -Select--- v (c) A 35.0 lb weight is substituted for the 12.0 lb weight.
