an experimental rocket plane lands on skids on a dry lake bed. it is traveling at 80.0 m/s when it touches down, how far does it slide before it comes to a stop? assume the coeffcient of kinetic friction between the skids and the lake is .600

  • physics -

    initial K.E. = work done against friction

    (1/2)M Vo^2 = M*g*U*X

    U is the friction coefficient (0.600) Vo is the initial velocity
    Mass M cancels out.

    Solve for X

    X = Vo^2/(2*g*U)
