Harry Potter decides to take Pottery 101 as an elective to satisfy his arts requirement at Hogwarts. He sets some clay (m = 3.66 kg) on the edge of a pottery wheel (r = 0.640 m), which is initially motionless. He then begins to rotate the wheel with a uniform acceleration, reaching a final angular speed of 3.100 rev/s in 3.40 s. a) What is the speed of the clay when the initial 3.40 s has passed? b) What is the centripetal acceleration of the clay initially and when the initial 3.40 s has passed? c) What is the magnitude of the constant tangential acceleration responsible for starting the clay in circular motion?
