A 0.22-kg gerbil runs in place with a linear speed of 0.40 m/s on an exercise wheel that is shaped like a hoop and has a radius of 9 cm and a mass of 5.5 g. Find the angular momentum of the wheel after the gerbil jumps off the wheel and keeps running with the same speed of 0.40 m/s. Note that the angular momentum of the gerbil can be calculated by mvl, where l is the moment arm, the perpendicular distance from the center of the wheel to the extended line of the gerbil’s velocity vector.
