Answer:
A piece of wire is bent in the shape of a parabola y=kx2 (y−axis vertical) with a bead of mass m on it. The bead can slide on the wire without friction. It stays at the lowest point of the parabola when the wire is at rest. The wire is now accelerated parallel to the x−axis with a constant acceleration a.
