A cat rides a merry-go-round turning with uniform circular motion. At time t1 = 2.20 s, the cat's velocity is (3.80 m/s) i^ + (3.40 m/s) j^, measured on a horizontal xy coordinate system. At t2 = 5.10 s, its velocity is (-3.80 m/s) i^ + (-3.40) j^. What are (a) the magnitude of the cat's centripetal acceleration and (b) the magnitude of the cat's average acceleration during the time interval t2 – t1, which is less than a period of the motion?
