My teacher gave us practice questions for the midterm. Can't for the life of me remember how to do this. Any hints would be greatly appreciated. I'm not just trying to bum answers off you guys; I really don't know where to start. 1. The problem statement, all variables and given/known data Чs = .2 (the Ч is backwards - can't find a closer symbol, but you know what I mean) Чk = .1 A man is pulling a 100 kg crate to the right. Fman = 150 N a) What is the force? [er, not entirely sure what he means by this?] b) Fman to get the crate moving? c) Fman to move crate at constant speed? 2. Relevant equations Unknown 3. The attempt at a solution heh.
