1. The problem statement, all variables and given/known data An object is hung on the end of a vertical spring and is released from rest with the spring unstressed. If the object falls 3.42 cm before coming to rest, find the period of the resulting oscillatory motion. 2. Relevant equations 3. The attempt at a solution This was a homework question given and the answer is in the back of the book and it says T = .262 seconds. Now i have no clue how they got this because I thought that the period was related to the spring constant and the mass but not to the amplitude so how can we find T if neither k nor m is given?
