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

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