Aunstretched spring hangs from the ceiling with a length of 0.31 m. a 9.1-kg block is hung from the spring and the spring stretches to be 0.50 m long. how long will the spring be if a 3.3-kg block is hung from the spring? for both cases, all vibrations of the spring are allowed to settle down before any measurements are made.

As we know that spring force is given by

here we know that for the equilibrium of the mass suspended with the spring we have

so now we have

now we have

now we have another mass

m = 3.3 kg

again from above equation we have

so final length of the spring will be 0.38 m

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.
