An elephant was standing on a bridge. The mass of the elephant was 5,000 kilograms. (That is about ½ a ton.) If the gravitational acceleration for the elephant was about 10 m/s2, how much force did the bridge need to apply to the elephant so it wouldn't fall?

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.
