The 2-kg collar is released from rest while in position A and subsequently moves with negligible friction along the circular guide driven by the spring. Determine the magnitude of the velocity (m/s) of the collar when it reaches position B. The unstretched length of the spring is 0.2 m. B 0.2 m k = 600 N/m с 0.4 m

Also, determine the magnitude of the normal force (N) exerted by the guide on the collar when the collar reaches position B.
