A 6.5-kg bowling ball is attached to the end of a nylon (Young's modulus 3.7x10 N/m²) cord with a cross-sectional area of 3.8x10¹³ m². The other end of the cord is fixed to the ceiling. When the bowling ball is pulled to one side and released from rest, it swings downward in a circular arc. At the instant it reaches its lowest point, the bowling ball is 1.3 m lower than the point it was released from, and the cord is stretched 2.6x10 m from its unstrained length. What is the unstrained length of the cord? Hint: When calculating any quantity other than the strain, ignore the increase in length of the cord.

The other end of the cord is fixed to the ceiling. When the bowling ball is pulled to one side and released from rest, it swings downward
in a circular arc. At the instant it reaches its lowest point, the bowling ball is 1.3 m lower than the point it was released from, and the
cord is stretched 2.6x10 m from its unstrained length. What is the unstrained length of the cord?
Hint: When calculating any quantity other than the strain, ignore the increase in length of the cord.
