Homework Help: Newtons Three Laws and Force Question

  1. Sep 14, 2011 #1
    1. The problem statement, all variables and given/known data


    A rocket that weighed 98.1 N when put together on Earth is attached to a 1.00 x 10^3-kg signal relay in intergalactic space. The rocket develops a constant thrust (i.e., it pushes with a force) of 10.0 kN. Compute the resulting acceleration.


    2. Relevant equations

    a=F/m

    a=acceleration
    F=force
    m=mass

    3. The attempt at a solution
    10.0 kN --> 100 N
    100 N / (98.1 N )(1.00 x 10^3 kg) = 1019.367992



    The answer should be 9.90 m/s^2. I don't understand why it's not coming out to that though.

    Hi ahhh_david and welcome to PF.

    I don't understand this. 10.0 kN = 10,000 N not 100 N.
