ASAP!!! An astronaut in a spacesuit that is almost out of oxygen finds himself perfectly motionless only a few feet from his spaceship. In the weightlessness of space, how can he apply Newton's third law to use the tools on his belt to reach his spaceship?

Newtons Third Law:
When any two bodies interact, the force exerted by the first body on the second is equal and opposite to the force exerted by the second body on the first.
