A car is moving with a velocity of 16 m/s when the brakes are applied and the wheels lock (stop spinning). The car then slides to a stop in 37 m. Find the coefficient of kinetic friction between the tires and the road.

  • Physics -

    Initial kinetic energy equals the work done against friction.

    (1/2)MVo^2 = M*g*muk*X

    muk = Vo^2/(2*g*X) is the kinetic friction coefficient you are looking for. You do the numbers.
    X = 37 m
    Vo = 16 m/s
