i have a question where it asks me to find the uncertainty in a ball's postion (m=50g). i have that part all figured out, but then it asks me what the answer indicates about the relevance of quantum mechanics to macroscopic objects. (the answer was approx. 10^-32m, a very small uncertainty). i am having troubles understanding this. i'm not sure what to do. i know that HUP in general says that we can't know with certainty both the position and momentum of a particle at the same time, and the equation (delta x)(delta p) >h/4pi. i'm not sure where to go with this. any advice?
