# Angular acceleration

## Homework Statement

An airplane makes a circular turn of radius 9 km at a constant speed of 650 km/h. Calculate the magnitude of the plane's a. angular velocity, b. centripetal acceleration, c. angular acceleration, d. tangential acceleration

w = v/r
aR = w^2r

## The Attempt at a Solution

I found angular velocity to be 0.02rad/s and centripetal acceleration to be 3.62m/s^2

If the speed is constant would the angular and tangential acceleration be zero? I'm not sure that I am understanding the theory behind this.
