Net Force

  1. Aug 7, 2005 #1
    If you have a 25N sideways force on a 10kg box that moves at speed of 5 m/s, what is the formula? I used F = m*a and got it wrong. :confused:

    What are you being asked to find out?

    I am being asked to find the net force on the box.

    well, so far the only force acting on it is the 25 N,
    Is there friction?

    Also, if the box is moving with constant velocity, i.e. no acceleration, then the net force is zero.

    Well that makes sense....and probably why a HINT was put in there (HINT: Think about this a bit before writing down any equations!)
    So, I amanswering that the net force is O because of continual velocity and no acceleration.
    Thank you for your help
