the only unit vectors that had been provided were the acceleration of the purse is (1.70 m/s2)i + (4.60 m/s2)j *apparently those letters didn't show up in the earlier post.
Homework Statement
A purse at radius 1.90 m and a wallet at radius 2.60 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 (1.70 m/s2) + (4.60 m/s2). At that instant and in...
