## Homework Statement

A car is going around a corner with a radius of 68m. At one instant, its speed is 19m/s and its speed is increasing at a rate of 3.2m/s^2.

What are the angular speed and the angular acceleration of the car at this instant?

What is the total linear acceleration of the car?

If the angular acceleration remains constant, what will the radial acceleration be after 1.4s?

## Homework Equations

I got alpha=.047rad/s^2 for the first one with aTan/r=alpha

6.2 m/s^2 for the second with aRad^2+3.2^2 under square root

I am lost on the 3rd
