1. The problem statement, all variables and given/known data a box is pushed horizontally across a floor with a force of 70 N to the right. There is a friction force also acting on the box in the opposite direction of 18 N. if the box is displaced 8 meters. what is the net work done on the box? 2. Relevant equations W(net)= Fd cos (theta) 3. The attempt at a solution the net forces on the box in the horizontal direction is= 70N - 18N= 52N to the right Since its moving horizontally, which is 0 degrees. and im given displacement as 8 meters, and the force calculated above: w(net)= (52N)(8m) cos (0) = 416 joules Does this look right?
