Homework Help: Radius of curvature of track

  1. Sep 12, 2010 #1
    1. The problem statement, all variables and given/known data
    A train enters a curved horizontal section of track at 100 km/hr and slows down with constant deceleration to 15 km/hr in 12 seconds. An accelerometer mounted inside the train measures a horizontal acceleration of 2 m/s^2 when the train is 6 seconds into the curve. Calculate the radius of curvature of the track for this instant.

    2. Relevant equations

    3. The attempt at a solution

    What are the relevant equation? How is radius of curvature related to the acceleration?
