Question

If the angular speed of the wheel of a bicycle is 300 rad/s and the radius of the wheel is 0.2 m, then the linear speed of the wheel of the bicycle is

• A. 90 m/s
• B. 60 m/s
• C. 30 m/s
• D. 15 m/s

Answer 1

The correct option is B 60 m/s

Angular speed, ω = 300 rad/s
Radius of the wheel, r = 0.2 m
Let the linear velocity of the bicycle be v.
Now, v = rω
⇒ v = 300 × 0.2
⇒ v = 60 m/s


Hence, the correct answer is option (b).
