Problem: Your friend, sitting on a stool at rest, is handed a bicycle wheel (figure on left) of mass m = 2.0 kg and radius R. = 0.40 m, spinning with angular velocity w = <0, 12.0, 0> rad/s. Your friend then abruptly flips the wheel (figure on right) such that it continues to rotate with the same angular speed, but in exactly the opposite direction. What is your friend's angular velocity immediately after your friend flips the bicycle wheel? The bicycle wheel can be modeled as a hoop (Ihoop = mR²). Your friend can be modeled as a cylinder (Ieylinder = Mr²) of mass M = 68.0 kg and radius r = 0.36 m. 21.AO < 0, 12.00,0 > rad/s BO < 0, –1.74,0 > rad/s CO < 0, 1.74, 0 > rad/s DO < 0, –12.00,0 > rad/s EO None of the above

Question
Problem: Your friend, sitting on a stool at rest, is handed a bicycle wheel (figure on left) of mass m = 2.0 kg
and radius R. = 0.40 m, spinning with angular velocity w = <0, 12.0, 0> rad/s. Your friend then abruptly flips
the wheel (figure on right) such that it continues to rotate with the same angular speed, but in exactly the opposite
direction.
What is your friend's angular velocity immediately after your friend flips the bicycle wheel? The bicycle wheel can
be modeled as a hoop (Ihoop = mR²). Your friend can be modeled as a cylinder (Ieylinder = Mr²) of mass M =
68.0 kg and radius r = 0.36 m.
21.AO < 0, 12.00,0 > rad/s
BO < 0, –1.74,0 > rad/s
CO < 0, 1.74, 0 > rad/s
DO < 0, –12.00,0 > rad/s
EO None of the above
