A brass wire is 1.40 m long and has a cross-sectional area of 6.00 mm2. A small steel ball with mass 0.0800 kg is attached to the end of the wire. You hold the other end of the wire and whirl the ball in a vertical circle of radius 1.40 m. What speed must the ball have at the lowest point of its path if its fractional change in length of the brass wire at this point from its unstretched length is 2.0 * 10-5? Treat the ball as a point mass.
