    1. The problem statement, all variables and given/known data

    A small body of mass 0.51 kg is attached by a 0.52 m long cord to a pin set into the surface of a frictionless table top. The body moves in a circle on the horizontal surface with a speed of 2.1π m/s.
    (a) What is the magnitude of the radial acceleration of the body?
    m/s2

    (b) What is the tension in the cord?

    radial acceleratio is same as centripetal accelaration.

    aR=v2/r=w2r=wv

    Good luck!!
