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 3.0xx10^(-2)N. The length and radius of the collagen are, respectively, 2.5 and 0.091 cm, and Young's modulus is 3.1xx10^(6)N//m^(2). If the strtching obeys Hooke's law, what is the spring constant k for collagen ?

Answer»

`3.5xx10^(3)N//m`
`1.0xx10^(3)N//m`
`3.2xx10^(2)N//m`
`6.4xx10^(2)N//m`
