Elena puts her eggs in a cage made out of wood. The wood breaks during the landing, but the eggs survive. Which would be the best reason to
explain why this prevented her eggs from breaking?"
O Directs the energy of the impact towards the egg
O Decreases the velocity of the egg before it starts slowing down
O Increases the time that the egg slows down
O Decreases the time that the egg slows down.
O Directs the energy of the impact away from the egg
O Increases the velocity of the egg before it starts slowing down

I think the answer is Decreases the time that the egg slows down.

Explanation:

If not try it starts slowing down

O Increases the time that the egg slows down.

russian is not my first language, so i'm afraid i can't write out an answer in russian, but hopefully you can find a way to do so. here's my best translation of the problem: you're given a plot of a particle's position in one-dimensional space over time, and you're asked to find either the total distance traveled by the particle after 6 seconds had elapsed, or the total displacement of the particle after 6 seconds.

if you want the total distance traveled, you would first need to determine the particle's velocity as a function of time, then integrate that over the 6-second interval. we know the position function is quadratic with roots at 0 and 6, so we have

where is unknown. because the position is parabolic, there is symmetry about the midpoint at , and we know that

so that the position function is

which means the velocity is

then the total distance traveled is

so the total distance traveled is 20 m.

on the other hand, if you want to find displacement: the particle starts at and ends at , so its displacement is 0.
