A bicycle with wheels of radius 0.4 m travels on a level road at a speed of 8 m/s. What is the angular speed of the wheels?
A)10 rad/s
B)20 rad/s
C)($\pi$/10)rad/s
D)(10$\pi$)rad/s
E)(20/$\pi$)rad/s

Question

Quizplus · Accepted Answer

The linear speed of a point on the edge of the wheel is given by:

v = r × ω

Where r is the radius of the wheel and ω is the angular speed of the wheel.

Rearranging this equation, we get:

ω = v / r

Substituting the given values, we get:

ω = 8 m/s / 0.4 m = 20 rad/s

Therefore, the angular speed of the wheels is 20 rad/s. The correct answer is (B).
