Centre of rotation

  1. Dec 4, 2011 #1
    "A car is driving on a circular racetrack, which is inclined at an angle of 40 degrees to the horizontal. The centre of rotation for the track lies in the horizontal plane, and is 45 m from the centre fo the racetrack and 5.0 m above ground level. The car's tires have a coefficient of kinetic friction of 0.35. The car is driving at the maximum possible speed to stay in its position on the narrow track. All of a sudden, the car hits an oil slick and the coefficient of friction is reduced to 0. Where, relative to the centre of the track, does the car crash into the ground?"

    I need help visualizing this problem. Where exactly is this "centre of rotation for the track"?
    Thank you! :)

    Hi sparkle123! :smile:

    Your problem appears to be badly formulated.
    It should say:
    "The centre of rotation for the track lies in the horizontal plane, and is 45 m from the car and 5.0 m above ground level."

    Thanks I like Serena! :)

    so centre of rotation for the track = centre of track?
