Toy racing car moves with constant speed around the circle

Reference no: EM13647569

A toy racing car moves with constant speed around the circle. Whenits coordinates are x = 0, y = 3m its velocity is(6m/s)i. When it is at x= -3m, y= 0m what is itsvelocity and acceleration (use i, j, k notation togive your answer)?
