Question

A window washer pushes his scrub brush up a vertical window at constant speed by applying a force F as shown in the figure (Figure 1). The brush weighs 14.2 N and the coefficient of kinetic friction is 0.180. Part A Calculate the magnitude of the force F. Express your answer with the appropriate units. F = Value Units Part B Calculate the magnitude of the normal force exerted by the window on the brush. Express your answer with the appropriate units. N = Value Units Figure 53.1°
