Length of the incline

  1. May 13, 2009 #1
    1. The problem statement, all variables and given/known data

    A skier is gliding along at 3.12 m/s on horizontal, frictionless snow. He suddenly starts down a 16° incline. His speed at the bottom is 17.89 m/s.
    What is the length of the incline?


    2. Relevant equations

    Not sure how to start this and formula to be used.

    3. The attempt at a solution

    Put the start of the ramp at a height z=h and the end of the ramp at z=0. Now you can use energy conservation to determine the height. Knowing the height and angle of a right-angled triangle allows you to calculate the distance.

    The OP needs to show some effort in order to help with solving.

    I think the mass of the skier should be given to find the acceleration and solve.
