To A thin sheet of fibreboard weighs 60 N and lies on a rooftop, as shown in the figure, where - 3 mL-15 m, and b-24m. The coefficient of solid friction between the board and the root is o -0.1. Assume turbulent flow and consider the coutficient of friction, C;= 0.027 0.5pU 1. What wind velocity in m/s) will generate enough triction to dislodge the board? 2. What is the drag force (in N) on the fibreboard when the wind speed is 20 m/s? Xo U m/s Fibreboard Roof
