A window washer pulls herself upward using the bucket-pulley apparatus shown in the figure . The mass of the person plus the bucket is 63 kg. How hard must she pull downward to raise herself slowly at constant speed?

the rope connects to the bucket and her hands. Each side of that rope must hold have the total weight (mg). So, she holds 1/2 mg

Half the total weight. Goodness, typo
