A pendulum with a cord of length r = 1.05 m swings in a vertical plane (see figure). When the pendulum is in the two horizontal positions 0 = 90° and 0 = 270°, its speed is 4.95 m/s. a (a) Find the magnitude of the radial acceleration (in m/s2) for these positions. m/s2 (b) Find the magnitude of the tangential acceleration (in m/s?) for these positions. m/s? (c) Draw a vector diagram to determine the direction of the total acceleration for these two positions.
