Question

12.90) A 3 lb collar can slide on a horizontal rod which isfree to rotate about a vertical shaft. The collar is initially heldat A by a cord attached to the shaft. A spring constant 2 lb/ft isattached to the collar and to the shaft and is undeformed when thecollar is at A. As the rod rotates at the rate of d/dt=16rad/s, the cord is cut and the collar moves out along therod. Neglect friction and the mass of the rod.
ACTUAL PROBLEM----->12.91) For the collar of Prob. 12.90,assuming that the rod initially rotates at the rate of d/dt=12 rad/s, determine for position B of the collar a) thetransverse component of the velocity of the collar, b) the radialand transverse components of its acceleration, c) the accelerationof the collar relative to the rod. Spring is under the rod and the cord is above therod
