A window washer pulls herself upward using the bucket-pulley

Reference no: EM13544287

A window washer pulls herself upward using the bucket-pulley apparatus shown in Fig. 4-42. The mass of the person plus the bucket is 60 kg. (a) How hard must she pull downward to raise herself slowly at constant speed? If she increases this force by 12 percent, what will her acceleration be?
