## Homework Statement

Entrance and exit ramps for freeways are often circular stretches of road. As you go around one at a constant speed, you will experience a constant acceleration. Suppose you drive through an entrance ramp at a modest speed and your acceleration is 2.0 m/s

^{2}.

What will be the acceleration if you triple your speed?

Express your answer to two significant figures and include the appropriate units.

## Homework Equations

a = v

^{2}/R

## The Attempt at a Solution

Given that the initial acceleration is 2.0 m/s

^{2}, and a = v

^{2}/R...

I am not sure where to get started. R is not given, and v is not given. I know how to find

*a*theoretically, but since I do not have concrete values to start with besides acceleration, I do not know where to begin.

Thanks for any guidance.
