Question: Bead A slides along the positive x-axis with an initial speed and reaches position d. Bead B, with the same initial speed, slides along a curved wire beneath the x-axis under the influence of gravity and also reaches the position d as shown in Fig. 1. The path of bead B is a conventional curve such as a semicircle or a parabolic curve. Assuming the frictional force is negligible along both paths, which bead reaches d first?
