A worker with spikes on his shoes pulls on rope that is attachedto a box that is resting on a flat, frictionless frozen lake. Thebox has mass m, and the worker pulls with a constant tension T atan angle θ = 40 ∘ above the horizontal. There is a strong headwindon the lake, which produces a horizontal force Fw that is pointedin the opposite direction than the box is being pulled. Draw afree-body diagram for this system. Assume that the worker pulls thebox to the right. If the wind force has a magnitude of 30 N, withwhat tension must the worker pull in order to move the box at aconstant velocity?
