A purse at radius 2.00 m and a wallet at radius 3.00m travel in uniform circular motion on the floor of a merry-go-round as the ride turns. They are on the same radial line. At one instant, the acceleration of the purse is (2.00 m/s2) i + (4.00 m/s2)j. At that instant and in unit-vector notation, what is the acceleration of the wallet?
