In a completely elastic collision: Group of answer choices

none of these

momentum is conserved, but not kinetic energy.

kinetic energy is conserved, but not momentum.

neither momentum nor kinetic energy are conserved.

momentum and kinetic energy are both conserved.

kinetic

i'm so sorry if this is wrong i'm only in 6th grade xd

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!

explanation:

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
