38. The smooth rod is free to rotate in a horizontal plane on the vertical shaft. The 4-lb ball has an initial velocity of 30 in/s and is attached to the shaft by the cord. When the cord is cut, the ball moves to position B. Neglecting the mass of the rod, determine the (a) the radial and transverse components of the acceleration of the ball immediately after the cord is cut, (b) the acceleration of the ball with respect to the rod and (c) the velocity of the ball when it reaches position B. Be sure to include free-body and kinetic diagrams.
