In outer space, a constat net force of magnitude 140 N is exerted on a 32.5 kg probe initially at rest. (a) what acceleration does thie force produce? (b) how far does the probe travel in 10.0 s...

I got a which equals 4.31 m.s^2 but how do i solve for b

  • Physics - ,

    Use
    S=ut+0.5at2
    S=distance travelled
    u=initial velocity (=0)
    t=10 s.
    a=4.31 m/s/s

    g is not involved because it is in outer space.

  • Physics - ,

    where did you get the 0.5 ??

  • Physics - ,

    actually the formula says
    S=ut+at2/2
    (ut plus half at2)
    I now realize that the 0.5 is confusing.

  • Physics - ,

    and i did 0(10) + 0.5(4.31 m/s/s)(10)^2= 225.5 and that is not right because the answer is 215

  • Physics - ,

    You may have put in the wrong number on the calculator, because 431/2=215.5 ≈ 215

  • Physics - ,

    WTF man
