At the instant shown, a truck A, of weight WA = 31,000 lb, and a car B, of weight WB = 397...

At the instant shown, a truck A, of weight WA = 31,000 lb, and a car B, of weight WB = 3970 lb, are traveling with speeds υA = 35 mph and υB = 34 mph, respectively.

Choosing point O as the moment center, determine the angular momentum (with respect to O) of the particle system formed by A and B at this instant.
