When you get new tires installed on your car the wheels are carefully balanced by placing small weights around the outside of the rim. If one of these weights falls off, your car may vibrate violently when you drive at certain speeds. This vibration occurs for speeds at which
A. the vibration frequency of the off-balance wheel matches the frequency at which the car likes to vibrate allowing a resonant energy transfer between the two.
B. the rotational kinetic energy of the wheel exactly matches the translational kinetic energy of the car, allowing a resonant energy transfer between the two.
C. the vibrating wheel acts like a harmonic oscillator.
D. the amplitude of the vibrating wheel becomes large enough to overcome the inertia of the massive car.
