Homework Help: What is the radius of the track

  1. Sep 6, 2012 #1
    This porblem has been killing me. It's the last question that I have left on my homework assignment and it is due tonight at midnight.

    The car in the figure below travels a distance of 745 m along the track, and the driver finds that she has traveled through an angle of 475°. What is the radius of the track?

    Please help!

    Uh ... what track is that? (No figure included). Is it a circular track?

    This is a pre-calculus math problem, rather than an Introductory Physics problem. How many radians are there in 475 degrees?

    You really should read the forum rules on how to post homework problems and follow them.
