A70.0-kg astronaut pushes to the left on a spacecraft with a force f in "gravity-free" space. the spacecraft has a total mass of 1.0 x 10^4 kg. during the push, the astronaut accelerates to the right with an acceleration of 0.36 m/s^2. determine the magnitude of the acceleration of the spacecraft.

Explanation:

Given that,

Mass of the astronaut, m = 70 kg

Mass of the spacecraft,

Acceleration of the astronaut,

To find,

The magnitude of the acceleration of the spacecraft.

Solution,

The force acting on the astronaut is given by :

During the push, the astronaut accelerates as a result a reaction force will also act on the spacecraft. Let is the acceleration of the spacecraft. It can be calculated as :

(reaction force)

Therefore, the magnitude of the acceleration of the spacecraft is . Hence, this is the required solution.

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.
