Resultant force on a car

  1. Dec 20, 2015 #1
    1. The problem statement, all variables and given/known data
    Gavin is kicking one of his toy cars with a force straight ahead. the car weighs 1.2 kg and has friction free wheels so that the friction forces of the car is small when it has started. Gavin kicks his car with the force of 2.4 N. How large is the resultant force?
    2. Relevant equations
    No equation
    3. The attempt at a solution
    If there is no friction then the resultant force should be pointing forward but my book is saying that the resultant force is zero. why?

    Why don't you translate the problem into common English / Physics language so that all can understand it? Perhaps the verb "to crackle" means something non-obvious in this punk-speak dialect? And power certainly isn't measured in Newtons in any unit system that I'm aware of. So how are we to know what "resultant" or "force" really translate to?
