Suppose an impulsive force F acts horizontally to the right at point O (the center of oscillation) in Fig. 17-12. Assume that the pendulum is initially at rest. (a) By combining the effects of translation and rotation, show that the resulting acceleration of a particle at point P is zero. (b) What do you conclude about the force at P that results from the applied force F? Because of this property, the center of oscillation is often called the center of percussion.
