Create your poster. a) On the poster board, draw a roller coaster track that starts with one large hill, followed by a valley, and then another, smaller hill.
b) Draw a cart in four different positions on the track, as outlined below.
i. First, draw the cart at the top of the first hill. Label it A.
ii. Second, draw the cart going down the first hill, into the valley. Label it B. iii. Third, draw the cart at the bottom of the valley. Label it C.
iv. Last, draw the cart at the top of the second, smaller hill. Label it D.
c) Draw an energy pie chart above each of the cart’s four positions.
i. Choose your reference point for determining height.
ii. Create a pie chart that accurately represents the ratio of the three forms of energy and label the sections of the pie Eg for gravitational potential energy, Ek for kinetic energy, and Eth for thermal energy. iii. Make sure your name is on the poster.

Step 3: Type one to two paragrap

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

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.

conservation of mass

mass before something happens = mass afterwards
