Pad 10:08 AM - 55% Need Help? Read It 5. + -13 points SerPSET9 11.P.014 My Notes Ask Your Teacher Heading straight toward the summit of Pikes Peak, an airplane of mass 10000 kg flies over the plains of Kansas at nearly constant altitude of 4.30 km with a constant velocity of 155 m/s west (a) What is the airplane's vector angular momentum relative to a wheat farmer on the ground directly below the airplane? j kg-m2/s (b) Does this value change as the airplane continues its motion along a straight line? O yes O no (c) What is its angular momentum relative to the summit of Pikes Peak? kg-m2/s Need Help?

Explanation / Answer

Angular momentum= NVR

A.m. = 10000×155×(4300-0) = 6665×10^6 kg.m^2/s

B). Yes this value will change as the plane moves ahead with constant angular velocity because magnitude of r vector changes w.r.t to farmer.

C). Angular momentum relative to peak is zero
