Homework Help: Roller coaster displacement physics problem

  1. Sep 11, 2006 #1
    here's the question
    a roller coaster moves 85m horizontally, then travels 45m at an angle of 30.0 degrees above the horizontal. What is its displacement from its starting point?

    can anybody help me do this?

    To add displacement vectors, add their horizontal and vertical components and then use the Pythagorean theorem to determine the length.
