Question

a toy is running at a speed of 10m/s. if the radius of wheel of the toy be 45 cm,find the angular speed of the wheel

Open in App

Solution

Radius of the wheel of the toy, r = 45 cm = 0.45 m
The linear velocity of the wheel, v = 10 m/s
As the linear velocity is related to the angular velocity as:
v = ωr
⇒ω = v/r = 10/0.45 = 22.22 rad/s
