a 12-lb collar is attached to a spring anchored at point C and can slide on a friction-less rod forming a 30 degree angle with the vertical. The spring hasconstant k and is unstretched when the collar is at A. Knowing that the collar is releasted from rest at A, determine the velocity of the collar at point B forvalues of k ranging from.1-lb/in to 2.0-lb/in.
to imagine the diagram, the collar at point A (unstretched) is on the same x-axis as the anchor @ C, while the collar point B (stretched) is located downwards-leftto point A, forming a 30 degree angle with the y-axis (vertical). In other words, the collar connecting points A and B is 30 degrees from the vertical/y-axis.
