An 80.6 kgastronaut is working on the engines of his ship, which is driftingthrough space with a constant velocity. The astronaut, wishing toget a better view of the Universe, leaves the ship and much laterfinds himself 29.2 m behind the ship(Relative velocity between the astronaut and the ship is zero).Without a thruster, the only way to return to the ship is to throwhis 0.498 kg wrench directly away fromthe ship. If he throws the wrench with a speed of 19.9 m/s relative to the ship, how long does it take the astronaut to reach the ship?
