Homework Help: Nonconservative Forces problem

  1. Mar 26, 2009 #1
    1. The problem statement, all variables and given/known data
    Suppose that the surfaces described are not frictionless and that the coefficient of kinetic friction between the block and the surfaces is 0.30. The block has an initial speed 7.0m/s and slides 2.0 m before reaching the ramp. Find (a) the speed of the the block when it reaches the ramp, and (b) the distance the the block slides along the inclined surface before coming momentarily to rest.(Neglect and energy dissipated along the transition curve.)

    2. Relevant equations
    Not sure, this is where I am lost.

    3. The attempt at a solution

    What's the friction force at each point of the surface? Consider the work done by the friction force.
