    Your SUBJECT is not 11th grade.

    yes it is

  • 11th grade -

    acceleration= V^2/r


    so acceleration= PI^2*4*r/14.3 put r in.

    check my algebra.

  • 11th grade -

    Centripetal Acceleration = v^2/r
    = (circumference/time)^2/r
    = (2*pi*r/t)^2)/r
    = ((2*3.14*50/14.3)^2)/50
    = 9.64 m/s^2

    Thank you! you are correct @carey
