The non-player characters with whom the player forms Social Links, a game mechanic wherein the player fosters friendships with the characters to unlock more powerful Personas, had no models in their creation, but Soejima had vague memories about their actions based on his experience when first hearing the ideas. With the series now taking place in a fictional rural town rather than a city like in the prequels, the characters with origins from the city had hair styles different from those in Inaba with 1UP.com commenting that Yu's and Yosuke's were more stylish. Shigenori Soejima was in charge of designing the characters in Persona 4. The English voice acting work was also met with a similar response. This included the characters' realistic personalities and the relationships established across the game. Reception of the game's characters are mostly positive, with various characters having been reviewed favorably. The general approach to designing the characters and ultimately the setting of the game was by drawing from the memory and interpretation of the development staff about a "rural, countryside" setting. ![]() ![]() Shigenori Soejima acted as the art director for the game and was responsible for the character design. A fighting game sequel, Persona 4 Arena, features the Investigation Team in a tournament competing against each other as well as characters from the previous game in the series, Persona 3. The game was also ported for the PlayStation Vita and PC as Persona 4 Golden which expanded various of the characters' stories and included a new one called Marie, a teenage girl linked with the Investigation Team. Persona 4 has been adapted to a manga and an anime series that gave different portrayals to the game's cast, most notably the protagonist who is given his own name and a personality. He is met by Yosuke Hanamura, the son of the local department store manager Chie Satonaka, an energetic girl with a strong interest in kung fu Yukiko Amagi, a calm and refined girl whose family owns the local inn Kanji Tatsumi, a first-year student whose punk reputation hides a softer side Teddie, a mysterious figure from the TV world who exists in the form of a cartoonish bear costume Rise Kujikawa, a popular teen idol who has taken a break from showbiz and Naoto Shirogane, a well-known junior detective. The protagonist is Yu Narukami, a high-school student who moved into the town from the city. The case is linked by the TV world, a dimension where the characters use alter-egos known as "Personas" to defeat the Shadows, beings that represent people's hidden thoughts that killed the first two victims. The plot of Atlus's PlayStation 2 role-playing game Persona 4 is centered on a group of high-school students dedicated to capturing the culprit responsible for the murders and kidnappings that happened in their small town of Inaba starting on April 11, 2011. From left to right Teddie, Rise, Yosuke, Naoto, Kanji, Yu, Chie, and Yukiko. Playable characters of Persona 4, backed by their Personas. ![]() ![]() Hint 1. How to approach the problem Recall your results found in the previous parts, namely the fact that the instantaneous velocity of the particle is constant. Which graph represents a variable that always has the same constant value at any time?Ĭorrect Whenever a particle moves with constant nonzero velocity, its x vs. t graph is a straight line with a nonzero slope, and its v vs. t curve is a horizontal line. ![]() ![]() Part D Which of the graphs shown is the correct v vs. t plot for the motion described in the previous parts? Physically, this means that the instantaneous velocity of the particle is constant over the entire time interval of motion. This is true for any motion where distance increases linearly with time.Īnother common graphical representation of motion along a straight line is the v vs. t graph, that is, the graph of (instantaneous) velocity as a function of time. In this graph, time t is plotted on the horizontal axis and velocity v on the vertical axis. Note that by definition, velocity and acceleration are vector quantities. In straightline motion, however, these vectors have only one nonzero component in the direction of motion. Thus, in this problem, we will call v the velocity and a the acceleration, even though they are really the components of the velocity and acceleration vectors in the direction of motion. ANSWER: Ĭorrect The instantaneous velocity of a particle at any point on its x vs. t graph is the slope of the line tangent to the curve at that point. Since in the case at hand the curve is a straight line, the tangent line is the curve itself. Hint 1. Graphical interpretation of instantaneous velocity The velocity of a particle at any given instant of time or at any point in its path is called instantaneous velocity. In an x vs. t graph of the particle's motion, you can determine the instantaneous velocity of the particle at any point in the curve. The instantaneous velocity at any point is equal to the slope of the line tangent to the curve at that point. Part C What is the instantaneous velocity v of the particle at t Hint 2. Slope of a line The slope m of a line from point A, with coordinates (t A, x A ) , to point B, with coordinates (t B, x B ) , is equal to the "rise" over the "run," or m=Ĭorrect The average velocity of a particle between two positions is equal to the slope of the line connecting the two corresponding points in an x vs. t graph. In an x vs. t graph, then, the average velocity equals the slope of the line connecting the initial and final positions. Hint 1. Definition and graphical interpretation of average velocity The average velocity v av of a particle that travels a distance Δx along a straight line in a time interval Δt is defined as v av = Part B What is the average velocity v av of the particle over the time interval ΔtĮxpress your answer in meters per second. Hint 2. How to read an x vs. t graph Remember that in an x vs. t graph, time t is plotted on the horizontal axis and position x on the vertical axis. For example, in the plot shown in the figure, x = 16.0 m at t = 10.0 s. Hint 1. Total distance The total distance Δx traveled by the particle is given by the difference between the initial position x 0 at t = 0.0 s and the position x at t = 50.0 s. In symbols, Δx = x − x 0 Part A What is the total distance Δx traveled by the particle? Express your answer in meters. Refer to this graph to answer Parts A, B, and C. Now let's study the graph shown in the figure in more detail. Note that an x vs. t graph like this does not represent the path of the particle in space. An example of a graph of position as a function of time for a particle traveling along a straight line is shown below. Mathematically, this corresponds to plotting the variable x as a function of t. What x vs. t Graphs Can Tell You To describe the motion of a particle along a straight line, it is often convenient to draw a graph representing the position of the particle at different times. This type of graph is usually referred to as an x vs. t graph. To draw such a graph, choose an axis system in which time t is plotted on the horizontal axis and position x on the vertical axis. Then, indicate the values of x at various times t. When a 1984 Alfa Romeo Spider sports car accelerates at the maximum possible rate, its motion during the first 20 s is extremely well modeled by the simple equation $$v_$ more than your answer, showing that this model is very good, but not perfect.Ch 02 HW Due: 9:30am on Monday, February 8, 2016 You will receive no credit for items you complete after the assignment is due.
