This figure (Ja] - 25.0 m/s") represents the total acceleration of a particle moving clockwise in a circle of radius r = 2.20 m at a certain instant of time. 30.0 (a) For that instant, find the radial acceleration of the particle m/s2 ( toward the center) (b) For that instant, find the speed of the particle. m/s (c) For that instant, find its tangential acceleration. m/s" (in the direction of the motion)
