Magnitude of cars acceleration

  1. Apr 1, 2012 #1
    A car is traveling counterclockwise along a circular bend in the road with an effective radius of 180 m. At a certain instant, the car’s speed is 26 m/s, but it is slowing down at a rate of 1.0 m/s2. What is the magnitude of the car’s acceleration?

    I thought it was v^2/r but that isnt the answer apparently.

    Hi Fr3sherthanu! Welcome to PF! :smile:

    (try using the X2 button just above the Reply box :wink:)
    that's the centripetal acceleration

    what about the tangential acceleration?​

    I dont even know what that is or how to go about finding that.
