Magnitude of acceleration of a speck of clay

  1. Mar 10, 2010 #1
    What is the magnitude of the acceleration of a speck of clay on the edge of a potter's wheel turning at 48 (revolutions per minute) if the wheel's diameter is 34 ?

    I tried using V=2(3.14)r/T then using ar =v2/r but i keep getting the wrong answer.

    Hi, Manny, welcome to PF!. You seem to be on the right track, why don't you show your numbers and someone will correct your math. What about the units??
