Find the kinetic coefficient of friction (mu)

[Abhishek Gupte]

Homework Statement

A 1.0x10^3 kg elevator carries a maximum load of 800kg
Velocity = 3m/s
Distance = .01km
Net work = 13640J

Homework Equations

Force of friction = (m)(mu)(gravity)

The Attempt at a Solution

Gravity = friction
9.8 = (mu)(17640)
.001 = mu
