1. The problem statement, all variables and given/known data Two masses of 4kg and 6kg are hanging from a pulley which is hung by a string. Initially the system is locked (the pulley is not allowed to rotate), and then it is released. Find the ratio of tension in the string holding the pulley before and after release. 3. The attempt at a solution How the heck will the tension change? Wont it be the same?
