A 70.0-kg astronaut pushes to the left on a spacecraft with a force   in "gravity-free" space. The spacecraft has a total mass of 1.0 × 104 kg. During the push, the astronaut accelerates to the right with an acceleration of 0.36 m/s2.

Determine the magnitude of the acceleration of the spacecraft.

    newtons 2nd law states F =m*A

    Astronaut: F = 70*0.36 = 25.2 N

    Spacecraft: 25.2 = 10000 * a

    a = 25.2 / 10^4 m/s/s = 25.2*10^-4 = 0.00252m/s/s in a leftward direction
