An airplane of mass 2180 kg located 131 km north of U is

ying

272 km/hr in an easterly direction.

(a) What is the magnitude of the angular momentum (kg m2/s) with respect to U?

(b)what is the angular momentum with respect to U?

Angular momentum is M*V*R, since V is perpendicular to the R vector.

Convert V to m/s and R to meters before multiplying.

Except for including the direction of angular momentum, your two questions are the same. Get it from the cross product VxR and the right-hand rule
