As indicated in the figure, a steel ball (m 200 g) is attached to a massless elastic cord which is initially not stretched. When the ball is released from rest at A, t slides without friction through a thin curved tube with constant radius of curvature r = 70.0 cm. The cord stretches as the ball slides down the tube and follows the curvature of the surface, as indicated by the thick dashed line in the figure. Furthermore, the cord...
