As seen in FIGURE 3, the ring weighing P (kg) passes from A to
the right with a velocity vA (m / sec) and moves downward on a flat
surface curved bar. The unstretched length of the spring attached
to the ring is X (mm) and the spring stiffness is k (N / m). Point
B is located just above the lower end of the curved part of the
rod. Determine the speed of the ring when the ring reaches point
B.
take P = 4
vA = 8
, X = 110 , hA = 180 , r = 180 and k =
