    Centripetal Acceleration with infinite Radius??

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

    Find centripetal acceleration given speed is 38m/s and radius is infinity large




    3. The attempt at a solution

    So The answer would get infinitely smaller so is zero the best answer?

    I would say so, but usually even if it was considered infinitely large it would still have a centripetal acceleration e.g. r = 40 km.

    However, how the question states it, r→ ∞ so v2/r → 0.
