Question

A purse at radius 1.70 m and a wallet at radius 2.50 m 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 (1.90 m/s2) + (3.00 m/s2). At that instant and in unit-vector notation, what is the acceleration of the wallet?
