An 85.0 kg astronaut is working on the engines of a
spaceship that is drifting through space with a con-
stant velocity. The astronaut turns away to look at
Earth and several seconds later is 30.0 m behind the
ship, at rest relative to the spaceship. The only way
to return to the ship without a thruster is to throw a
wrench directly away from the ship. If the wrench
has a mass of 0.500 kg, and the astronaut throws the
wrench with a speed of 20.0 m/s, how long does it
take the astronaut lo reach the ship?

i dont think you are wrong for wanting to get even with someone who did you wrong.

(i'm an eye for an eye kind of person) but if this person hurt you in a sexual way, i dont suggest doing anything to him. he should be taken to the proper authorities, you could go to jail depending on what you do. if it was something small like your sibling took your spot on the couch, than yea, i would get even with him by taking one of his favorite snacks lol. but i dont suggest you doing anything illegal.
