SUMMARY
An astronaut in a space walk, after losing his tether, must utilize the principles of conservation of linear momentum to return to his spacecraft. The discussion highlights that using a wrench as a paddle is ineffective due to the lack of a medium to push against in the vacuum of space. Instead, the astronaut can throw the wrench in the opposite direction to propel himself back towards the ship, effectively applying the equation p=mv, where momentum (p) is the product of mass (m) and velocity (v).
