All of the following are examples of energy transformations EXCEPT OB O A. Electric energy from an outlet becomes electromagnetic energy when it is used to power a light bulb. Ajack in the box is cranked down until the spring inside is compressed. The spring releases turning elastic potential energy into kinetic energy when the toy moves. O C. Stored potential energy in a lighter is ignited to create light and thermal energy. OD. A child on a sled posesses kinetic energy as they slide down a snowy hill.​

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.
