A high-speed lifting mechanism supports a(n) 860-kg object with a steel cable that is 22.0 m long and 4.00 cm in cross-sectional area. (a) Determine the elongation of the cable. (Enter your answer to at least two decimal places.) mm (b) By what additional amount does the cable increase in length if the object is accelerated upwards at a rate of 3.2 m/s? mm (c) What is the greatest mass that can be accelerated upward at 3.2 m/s if the stress in the cable is not to exceed the elastic limit of the cable, which is 2.2 x 108 Pa? kg A high-speed lifting mechanism supports a(n) 860-kg object with a steel cable that is 22.0 m long and 4.00 cm in cross-sectional area.
