1. The problem statement, all variables and given/known data finding the lowest non zero acceleration in a lab 2. Relevant equations 3. The attempt at a solution the question has asked to find the lowest non zero acceleration, I can't find what nonzero acceleration exactly is. does that mean the acceleration rate is any given number besides 0? if an object is moving in one direction because of the initial velocity and then reverses directions because of a fan and the acceleration rate is -.048 the entire time the object is in motion before it hits a wall, does that mean that is a non zero acceleration rate? or would I need to find the lowest positive acceleration rate of the object when it is just moving in the one direction?
