Homework Help: Im trying to work out the acceleration and ave velocity for a model helicopter

  1. Mar 28, 2012 #1
    1. The problem statement, all variables and given/known data

    The chopper is 700g and is being pushed with a 10N force(thrust), it flies for 10 secs

    2. Relevant equations

    I need to work out the ave acceleration, velocity and distance travelled after 10 secs

    3. The attempt at a solution

    im sure im doing something wrong, i know
    a=Fnet/mass which gives a=10N/.7 = 14.28m/s/s
    velocity final = V=Vi+at = V=142.8ms
    ave velocity = 1/2(Vi-Vf) = 71.4ms
    distance = 71.4ms x 10 secs = 711m

    It just seems to high a number, any help wuould be greatly appreciated

    apart from a small discrepancy [a few meters] in your distance calc, it all look good to me.
