The tolerance is -+2% Flying Circus of PhysicsContinuation of Problem 8 and Problem 37. Another explanation for the sliding stones of Racetrack Playa in Death Valley, California isthat the stones move only when the water dumped on the playa during a storm freezes into a large, thin sheet of ice. The stones aretrapped in place in the ice. Then, as air flows across the ice during a wind, the air-drag forces on the ice and stones move them both,with the stones gouging out the trails. The magnitude of the air-drag force on this horizontal "ice sail" is given by Dice = 4CicepAicev²,where Cice is the drag coefficient (2.0 × 103), p is the air density (1.21 kg/m³), Aice is the horizontal area of the ice, and v is the windspeed along the ice.Assume the following: The ice sheet measures 210 m by 540 m by 4.8 mm and has a coefficient of kinetic friction of 0.15 with theground and a density of 917 kg/m³. Also assume that 100 stones of mass 17 kg are trapped in the ice. To maintain the motion of thesheet, what is the required wind speed near the sheet?Number iUnits
