A child slides across a floor in a pair of rubber-soled shoes. The friction force acting on each foot is 20 n, the footprint area of each foot is 14 cm2, and the thickness of the soles is 5. 0 mm. Find the horizontal distance traveled by the sheared face of the sole. The shear modulus of the rubber is 3. 0x 106 pa.
