Question

A bicycle wheel with a radius of 0.62 m rotates with an angular speed of 12 rad/s about its axle, which is at rest. What is the linear speed of a point on the rim of the wheel?

Answer 1

The linear speed of a point on the rim of the wheel is 7.44 m/s

Explanation:

It is given that

Radius of the bicycle wheel (R) = 0.62 m

Angular speed = 12 rad/s

To find the linear speed

V= ω × R

Where,

ω is angular speed

R is the radius

V = 12 × 0.62

V =7.44 m/s.

Hence, the linear speed of a point on the rim of the wheel is 7.44 m/s
