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/s2.
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 = v2/R
The Attempt at a Solution
Given that the initial acceleration is 2.0 m/s2, and a = v2/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.
