    How Hard Must a Window Washer Pull to Raise Herself at Constant Speed?

    A window washer pulls herself upward using a bucket-pulley apparatus. How hard must she pull downward to raise herself slowly at constant speed? If she increases this force by 10% what will her acceleration be? The mass of the person and bucket is 65 kg. Need some help, gracias.
