A particle describes an UCM(uniform circular motion) with period 0.500 s and circle centered at the origin of the x and y coordinate system. Let î and ȷ be the unit vectors along the x and y directions, respectively. At instant t=0 the particle's acceleration vector (in m/s2) is a =2.30î. What is its acceleration vector (in m/s2) at time t=2.50 s?
