Homework Help: The Law of Motion

  1. Oct 1, 2007 #1
    An 850 kg car is moving to the right at 1.44 m/s. What is the net force on the car ?

    I am totally off on this problem ! Can someone help ?
    And in the problem above, it is different when the car moving left ?

    Thanks

    The problem appears incomplete. I am assuming that it means a "constant velocity" to the right at 1.44 m/s.

    No matter what it is, or which way it's going, or how fast it's going...

    if an object is going at a constant velocity, what is its acceleration, and what's the net force on it?

    Is that the acceleration is 0, and i don't really know what is net force is ? That why i asked

    Go read Newton's first and second law.
