# Question: A pendulum swinging in a circular arc under the influence

A pendulum swinging in a circular arc under the influence of gravity, as shown in Fig. 7.35, has both centripetal and tangential components of acceleration.

(a) If the pendulum bob has a speed of when the cord makes an angle of θ = 15o 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?
