An astronaut with a mass of 85 kg is outside a space capsule when the tether line breaks. to return to the capsule, the astronaut throws a 2.0 kg wrench away from the capsule at a speed of 14 m/s. at what speed does the astronaut move toward the capsule?

Using the work energy theorem. what is the velocity of a 850kg car after starting at rest when 13,000j of work is done to it.
