A 3 m 4 m |B A 1.69-kg collar is attached to a spring and slides without friction along a circular rod in a horizontal plane. The spring has an undeformed length of 3.8m. and a constant k= 1.69KN/m. Knowing that the collar is in equilibrium at A and is given a slight push to get it moving, determine the velocity of the collar (a) as it passes through B, (b) as it passes through C.
