QUESTION
A window washer pulls herself upward using the bucket-pulley apparatus. How hard must she pull downward to raise herself slowly at constant speed?
A window washer pulls herself upward using the bucket-pulley apparatus. How hard must she pull downward to raise herself slowly at constant speed? The mass of the person plus the bucket is 74 kg. I calcuated this by multiplying (74 kg)(9.81 m/s/s). Now, If she increases this force by 13%, what will her acceleration be? The mass of the person plus the bucket is 74 kg.
