Question

if a wheal rotates at a angular speed of 2 rad/s, what is linear speed of it?

Answer 1

v=\[\omega\]*r

Answer 2

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

Answer 3

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

Answer 4

exactly

Answer 5

what if the radio is 20m? is the answer 40m/s?

Answer 6

yup

Answer 7

Ok clear now. Thanks
