A 1-lb ball A and a 2-lb ball B are mounted on a horizontal rod which rotates freely about a vertical shaft. The balls are held in the positions shown by pins. The pin holding B is suddenly removed and the ball moves to position C as the rod rotates. Neglecting friction and the mass of the rod and knowing that the initial speed of A is 8 A v = ft/s, determine

(a) The radial and transverse components of the acceleration of ball B immediately after the pin is removed,

(b) The acceleration of ball B relative to the rod at that instant,
