Homework Help: Calculate distance from force HELP

  1. Oct 10, 2007 #1
    Calculate distance from force HELP!!!

    In outer space, a constant net force of magnitude 135N is exerted on a 30.2kg probe initially at rest. What acceleration does this force produce? How far does the probe travel in 6.00s

    what i have so far is that F=Ma
    where the force is 135N=30.2a solve for a and get 4.47m/s.

    now this is where i get lost. to find the distance im assuming that it travles 4.47m/s so the gerneal idea i got was to multiply by 6.00s and get 26.82m. This answer is incorrect any one have any ideas?

    ok i got it i figured it out
    i had to use a seperat equation where X=Vot + .5(a)(t)^2

    x=0(6)+ .5(4.47)(6)^2
    solve all that for X and i got 80.46 m and this answer is correct.
