a piece of clay with a mass of 0.30 kg is tied to the end of a string 6.5 meters in length, and then whirled around in a horizontal circle at a speed of 6 m/s. a. what is the centripetal acceleration of the clay? b. what is the tension of the string?
the string provides the centripetal force
a. a = v^2 / r
b. f = m v^2 / r
