Reexamine Example 4.10 by choosing ➀ to be the same as that in the example and ➁ to be an arbitrary position after release. Determine the speed of A as a function of yA, and plot the kinetic energy of A as a function of yA. Use this plot to argue that the cord connecting A and B never goes slack between the instant of release and the impact of B with the ground. Hint: To argue that the cord remains taut between the positions of interest, you may want to look at concept Prob. 4.21 on p. 274.
