# 42. A pendulum with a cord of length r 1.00 m swings in a vertical plane (Fig. P4.42) When the pendulum is in the two horizontal positions 0 90.0° and 0 270°, its speed is 5.00 m/s. Find the magnitude of (a) the radial acceleration and (b) the tangential accel eration for these positions (c) Draw vector diagrams to = determine the direction of the total acceleration for these two posiions. (d) Calculate the magnitude and direction of the total acceleration at these Figure P4.42 two positions
