A 70.0kg astronaut pushes to the left on a spacecraft with a force in "gravityfree" 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
