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 3.0 × 10-² N. **89. The length and radius of the collagen are, respectively, 2.5 and 0.091 cm, and Young's modulus is 3.1 × 10° N/m². (a) If the stretching obeys Hooke's law, what is the spring constant k for collagen? (b) How much work is done by the variable force that stretches the collagen? (See Section 6.9 for a discussion of the work done by a variable force.)

A child slides across a floor in a pair of rubber-soled shoes. The frictional force acting on each foot is 20.0 N. The footprint area of each shoe sole is 11.0 cm, and the thickness of each sole is 5.80 mm. Find the horizontal distance by which the upper and lower surfaces of each sole are offset. The shear modulus of the rubber is 3.00 x 10 N/m2. Your response differs significantily from the correct answer. Rework your solution from the beginning and check each step carefully. mm Need Help?Read i
