Homework Help: I have a question about Kinetic and Potential Energies.

  1. Mar 16, 2013 #1
    Question: The top of a chute whose length is 12 meters is 3 meters vertically above its lowest point. A parcel of mass 1.6 Kilogram slides from rest from the top of the chute and reaches the lowest point with a speed of 5 meters per second. Calculate, for the the parcel:

    (A) The gain in Kinetic Energy.
    (B) The loss in Potential energy.
    (C) The Work done in overcoming the frictional resistance.
    (D) The average value of this resistance (force of friction).
    1. The problem statement, all variables and given/known data

    2. Relevant equations
    KE and PE equations obviously.

    3. The attempt at a solution
    No idea. please everyone have a go at this.

    Treat the "chute" as an inclined plane which the parcel slides down.
