T(0) = 800 m and T(40) = 200 m: Understanding Linear Decay in Motion In physics and engineering, understanding motion involves analyzing how variables like distance, velocity, and time interact over specific intervals. One common concept is the linear decrease in a quantity over time — illustrated by a simple but insightful formula:
T(t) = 800 − 15×t, where T represents distance (in meters), and t is time (in seconds). If we examine this function at two key moments — t = 0 seconds and t = 40 seconds — we uncover meaningful insights about deceleration or consistent removal of distance over time. ---
