Homework Help: Find the kinetic coefficient of friction (mu)

  1. Apr 12, 2017 #1
    1. The problem statement, all variables and given/known data
    A 1.0x10^3 kg elevator carries a maximum load of 800kg
    Velocity = 3m/s
    Distance = .01km
    Net work = 13640J

    2. Relevant equations
    Force of friction = (m)(mu)(gravity)

    3. The attempt at a solution
    Gravity = friction
    9.8 = (mu)(17640)
    .001 = mu
