A net force of 4 . 5 N acts on the object. What is the magnitude of the angular mo mentum bardbl vector L bardbl of the object with respect to an axis perpendicular to the circle and through its center? 1. bardbl vector L bardbl = 18 N · m kg 2. bardbl vector L bardbl = 13 . 5 kg · m 2 s 2 3. bardbl vector L bardbl = 12 m 2 s 4. bardbl vector L bardbl = 24 kg · m 2 s 5. bardbl vector L bardbl = 9 N · m kg 003 10.0 points A person spins a tennis ball on a string in a horizontal circle (so that the axis of rotation is vertical).
