Question

A car is moving with speed $3.5\text{m/s}$. If the radius of its tyre is $0.35\text{m}$, then calculate the angular velocity of the wheel of the car.

• A. $20\text{rad/s}$
• B. $11\text{rad/s}$
• C. $10\text{rad/s}$
• D. $25\text{rad/s}$

Answer 1

The correct option is C $10\text{rad/s}$

We have,
$v=r\omega$
Given,
$v=3.5\text{m/s},r=0.35\text{m}$
$\omega =v/r=10\text{rad/s}$
