(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A window washer pulls herself upward using the bucket-pulley apparatus:

The mass of the person plus the bucket is 63 kg.

(a) How hard must she pull downward to raise herself slowly at constant speed?

2. Relevant equations

F = m(a)

3. The attempt at a solution

I figured that since she wants to raise herself atconstantspeed, that makes her acceleration equal to zero. Which means Fnet=0=Ftension-Fgravity, so Ftension=Fgravity. F gravity=9.8(63)=617.4 N, but it says I have the wrong answer.

Thanks in advance for the help.
