A particle moves in a circular path of radius R = 2 m. At some instant of time, its total acceleration vector (ä) has magnitude 20 m/s? and makes an angle 0 = 30° with the radius as shown in the figure below. At that instant, the magnitude (in m/s²) of the particle's centripetal acceleration (a) is: A. 10 В. 2.4 С. 17.3 D. 5.4 E. 0.5 R. 92°C
