You and your friend are tasked with moving boxes into a storage unit. After becoming tired,
your friend decides it’s best to push the boxes on the level concrete floor. You observe them
pushing at a downward angle of 25 degrees below the horizontal on a 46 kg box. If the coefficient of
kinetic friction between the cardboard and concrete is μk = 0.18, what force are they
exerting to keep the box moving at a constant speed?
