Question

What is the angular speed of a car rounding a circular turn of radius 80m at 72km/h?

Answer 1

The angular velocity is `=0.25rads^-1`

Explanation:

Convert the speed in `ms^-1`

The speed is `v=72*1000/3600=20ms^-1`

The radius is `r=80m`

Apply the equation

`omega=v/r=20/80=0.25rads^-1`
