Exercise 111

A pendulum swinging in a circular arc under the influence of gravity, as shown in Fig., has both centripetal and tangential components of acceleration. (a) If the pendulum bob has a speed of 2.7 m/s when the cord makes an angle of = 15° with the vertical, what are the magnitudes of the components at this time (b) Where is the centripetal acceleration a maximum What is the value of the tangential acceleration at that location
