Homework Help: What is the maximum acceleration of this car on a concrete surface?

  1. Mar 14, 2008 #1
    Two-thirds of the weight of a 1500 kg car rests on the drive wheels. What is the maximum acceleration of this car on a concrete surface?

    (2/3) * 1500kg =1000kg
    but I need the force so I can find the acceleration. What do I do next?

    The force would be provided by friction. What's the coefficient of static friction between the tires and the concrete?

    I don't know the coefficient of friction. The question and all the information given is:

    Without the coefficient of friction (or a guess at it) you cannot solve the problem. Look to see if it's given in another part of your text.
