# A 3-lb collar can slide on a horizontal rod which is free to rotate about a vertical shaft.

A 3-lb collar can slide on a horizontal rod which is free to rotate about a vertical shaft. The collar is intially held at A by a cord attached to the shaft. A spring constant of 2 lb/ft is attached to the collar and to the shaft and is undeformed when the collar is at A. As the rod rotates at the rate ThetaDot=16 rad/s, the cord is cut and the collar moves out along the rod. Neglecting friction and mass of the rod, determine
a)the radial and transverse components of the acceleration at A
b)The acceleration of the collar relative to the rod at A
c)the transverse component of the velocity of the collar at B
