A window washer pulls herself upward using the bucket-pulley apparatus. The mass of the person plus the bucket is 69 kg.How hard must she pull downward to raise herself slowly at constant speed?If she increases this force by 11 percent, what will her acceleration be? There is ...

Physics
okay well i am confused about the way you can figure out the acceleration if the tension is increased by 11%

Physics
no since there is only one pulley then there is only one rope and if there is only one pulley and one rope there is only one tension

Physics
to get T would you just do 69(9.8)

A box is given a push so that it slides across the floor. How far will it go, given that the coefficient of kinetic friction is 0.15 and the push imparts an initial speed of 3.9 m/s?

physics
A box weighing 69 N rests on a table. A rope tied to the box runs vertically upward over a pulley and a weight is hung from the other end. Determine the force that the table exerts on the box if the weight hanging on the other side of the pulley weighs one of the following: a)...
