Homework Help: How to find acceleration from given 2 masses and acceleration?

  1. Feb 22, 2013 #1
    an astronaut (with a spacesuit) of mass 90 kg is tethered to a 750 kg satellite. By pulling on the tether, she accelerates toward the satellite at 0.55 m/s^2. What is the acceleration of the satellite toward the astronaut?

    I do not know how to start since im guessing gravity doesnt apply

    Why is the astronaut accelerating toward the space craft after pulling on the tether?
    Haven't you learned about forces and accelerations? Newton? Bueller?

    ok I got I now.
    I did ma=ma to find the missing acceleration.
