Q. 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 14.0 cm2, and the thickness of each sole is 4.10 mm. Find the horizontal distance by which the upper and lower surfaces of each sole are offset. The shear modulus of the rubber is 3.00 106 N/m2.

Q. Three children each of weight 356N make a long raft by lashing together logs of diameter .30m and length 1.8m. how many logs will be needed to keep them afloat in fresh water. take the density of the logs to be 800kg/m^3
