14. Two lab carts are on a frictionless track, attached by a spring, shown above. The carts are
pushed together by a physicist, therefore compressing the spring fully. The physicist lets go of the carts
and they move in opposite directions after the spring extends. Which of the following happens to the
cart/spring system after the carts are released?
a. The energy of the system decreases
b. The energy of the system remains constant
c. The momentum of the system increases
d. The momentum of the system remains constant.

0.3x0.21x0.08kg=mass 1 sheet

mass 500 = 500xmass 1

volume pile = 0.3x0.2x0.048

density=mass/volume= 500xmass 1/0.3x0.2x0.048

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.

no simpler subs form complex ones. synthesise = make
