# Missing info from this question? (Max. acceleration possible for a vehicle)

## Homework Statement

Two-thirds of the weight of a 2000 kg car rests on the drive wheels. What is the maximum acceleration of this car on a concrete surface?

## The Attempt at a Solution

Shouldnt I have been provided mu, the coeeficient for friction? Its a mastering physics question. Thanks

You can look up the value of $\mu$ in a table in the textbook.

IMO, you need more information. After all, top-fuel dragsters accelerate quicker than Pro Stock dragsters on the same surface (why?). And different rubber compounds have way different coefficients of friction on the same surface (asphalt or concrete, whatever).

Maybe if you just use variable names for the max engine power and for the max coefficient of friction, can you get full credit for the question?
