eration of p varies inits back-and-forth motion along the path. At X, Fig. 46, the ac-celeration of P being horizontal, the horizontal component of theacceleration is equal in magnitude to the acceleration itself. Inother words, at this extremity of the path the acceleration ofp is equal to the… … PX Fig. 4G. The acceleration at different points ofthe path. tude of the horizontal component diminishes. . Therefore, al-though p is approaching 0 with an increasing velocity, its ac-celeration is de-creasing. At Y theacceleration of P isdirected verticallydownward; and, asits horizontal…
