Question

Two of the tires on a tractor-trailer have 1.5 m diameters. If the tractor-trailer travels at a linear velocity of 3.0 m/s, what is the angular velocity of each tire?

Answer 1

I got `2"rad"/s`

Explanation:

I would use the relationship between linear velocity `v`, radius `r` and angular velocity `omega`:

`v=omegar`

Rearranging:

`omega=v/r=3/1.5=2"rad"/s`
