The angular velocity of the tire is 11.12 rad/s.
Angular velocity: This is the change in angular direction per time. The S.I unit is rad/s.
⇒ Formula:
- v = rω.................... Equation 1
⇒ Where:
- v = linear velocity of the car
- r = radius of the car
- ω = angular velocity of the car
⇒ Make ω the subject of the equation
- ω = v/r.............. Equation 2
From the question,
⇒ Given:
- v = 20 km/h = 20(1000)/(3600) m/s = 5.56 m/s
- r = 50 cm = 50/100 = 0.5 m
⇒ Substitute these values into equation 2
- ω = 5.56/0.5
- ω = 11.12 rad/s
Hence, The angular velocity of the tire is 11.12 rad/s
