## anonymous 5 years ago if a wheal rotates at a angular speed of 2 rad/s, what is linear speed of it?

1. anonymous

v=$\omega$*r

2. anonymous

linear velocity is angular velocity times the radius of the wheel.

3. anonymous

so if the radio is 20 cm, then the linear velocity will be 40 cm/s? am I right?

4. anonymous

exactly

Ok clear now. Thanks
