This figure (|| = 10.5 m/s2) represents the total acceleration of a particle moving clockwise in a circle of radius r = 2.40 m at a certain instant of time. (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/s2 (in the direction of the motion)
