1. The problem statement, all variables and given/known data You have a 4kg block attached to a string with T=35N. If the block begins at 5m/s and is lowered 10m what is approxaimate final velocity of block? So I got the question right: Find Fnet and times it by 10m and set (Fnet)(10)= work = KE and find velocity from KE. But my question is W= PE + KE so where is the PE? Thanks for the help.
