The speedometer on a car actually measures the rotational speed of the axle and converts that to the linear speed of the car, assuming the car’s tires diameter is 0.62 m. What is the rotational speed of the axle when the car is traveling 19 m/s?

Answer:

61.3 rad/s

Explanation:

Rotational speed = linear speed / radius

ω = v / r

ω = (19 m/s) / (0.62 m / 2)

ω = 61.3 rad/s
