Deceleration refers to the rate at which an object slows down over time. When an object is decelerating, it means that its velocity is decreasing.In the case of the hyena, deceleration is experienced as it moves away from the stream. The given rate of deceleration for the hyena is \(0.1 \mathrm{~m/s^2}\). This means that every second, the hyena's velocity reduces by \(0.1 \mathrm{~m/s}\). Understanding deceleration is important because it affects predictions of movement using mathematical models, such as the Taylor polynomial. In physics, deceleration is technically just a negative acceleration, and this is why it is represented with a negative sign in equations. Calculating the impact of deceleration accurately helps to determine how far the hyena will travel within a certain time frame.

Initial velocity is the speed at which an object is moving when first observed or measured. For the hyena running from the stream, the initial velocity \(v_0\) is \(2 \mathrm{~m/s}\).This initial velocity is an essential component of the Taylor polynomial used to estimate future positions of the hyena on the path. Knowing the initial velocity allows us to predict how far the hyena would travel without any forces acting on it, making it a crucial starting point for further calculations.For the hyena's situation, this speed combined with the deceleration will affect how quickly it will reduce its distance from the stream. The formula for calculating the position includes this initial velocity and how it changes over time.

Time interval refers to the duration over which changes in velocity and position are measured or estimated. In this example, the time frame is specified as \(1\) second.This is the period over which the deceleration affects the hyena's velocity and subsequently its position.Understanding the time interval is crucial as it sets the bounds for calculations that involve changes in speed and position. Knowing this time period helps to plug values into the formulas accurately, providing reliable estimates.In motion problems, the time interval guides the evaluation of future positions by dividing entire motion into manageable segments for analysis.

The second degree Taylor polynomial is a mathematical tool used to approximate the position of moving objects when they experience constant acceleration or deceleration. The polynomial is written as: \[ s(t) = s(0) + v(0) \cdot t + 0.5 \cdot a \cdot t^2 \]This formula calculates the hyena's position after a certain period, considering initial velocity, initial location, and constant deceleration. For this problem, analyzing motion with a second degree polynomial enables us to represent changes in both velocity and position without direct experimentation.Taylor polynomials offer a simplified, yet precise way to model changes for practical applications, predicting movement in real-life scenarios based on given initial conditions.
