arr, i am so confused, is that tangential accelaration?(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

A car starts from rest on a curve with a radius of 110 m and accelerates at 1.20 m/s^2. How many revolutions will the car have gone through when the magnitude of its total acceleration is 2.20 m/s^2?

2. Relevant equations

theta (final)=theta (initial)+omega*(delta)t+(a*(delta)t^2)/2*r

3. The attempt at a solution

i just have no idea how to figure out the time or the distance (or the angle) it takes the car to get from one acceleration to another...
