A cylindrically shaped piece of collagen (a substance found in the body in connective tissue) is being stretched by a force that increases from 0 to 2.73 10-2 N. The length and radius of the collagen are, respectively, 2.3 and 0.088 cm, and Young's modulus is 3.10 106 N/m2.

(a) If the stretching obeys Hooke's law, what is the spring constant k for collagen?
