FF Problem 4: A plane with a wingspan of d=2 3.6md:23.6m loses control in ight and begins to d spiral in a circle around the cockpit while in a vertical dive. It completes one rotation every T=3.625T=3.62s f'-1E]L'L'\\])crl\"Imam @3_33% Part (:1) Write the expression for the speed of the tips of the wings relative to the central axis of the plane. &_33% Part (1)) What is the speed in meters per second? &_33% Part (c) What is the centripetal force, in newtons, experienced by a pilot with a mass of 1 00kg100kg who is 1.0m1.0m above the axis of rotation. ' N Problem 5: A wind turbine blade with a radius of 21 m and a mass of 142.0 kg is rotating at .0. '5 rev/s. Assuming all of the mass is located at the end of the blade, what is the net force ( in N) acting on the end of the turbine blade? ( This net force supplied by interatomic forces in the metal is the centripetal force required to keep each atom in circular motion.)
