[SOLVED] Sliding in Socks 1. The problem statement, all variables and given/known data Suppose that the coefficient of friction between your feet and the floor, while wearing socks, is 0.250. Knowing this, you decide to get a running start and then slide across the floor. If your speed is 3.00 m/s when you start to slide, what distance d will you slide before stopping? 3. The attempt at a solution We are given that coefficient of friction is .250 f = .250(n) I really don't know to go from here. We are given speed so, let me permit my brain to flow with the numbers :D K= .5mv^2 may apply .250mg = .5m(.250)^2 .250(9.8)m = .5m(.250)^2 2.45m = .003125m................and it ends there..so I just went the wrong way. Solution is 1.84m, but I want to learn how to do this problem.
ok I got that k1 = .5mvo^2 k2 = .5mv^2 f = umg W = F *s we know that f is a F so I could use that so W = -fd = -umgd Wtotal = k2-k1 so I would think it would be safe to say taht k2-k1 = -umgd .5(mv^2) - .5(mvo^2) = -umgd is this is all correct thusfar, how do I continue?
yep got it, at first, I was confused on what to do with the m, and realized that they are common factor and cancel out.
