The discussion focuses on calculating the time required for a car traveling at 78 km/h to stop after covering a distance of 99 meters. The relevant equation used is Δx = 1/2 (vi + vf) * t, where Δx represents the distance, vi is the initial velocity, vf is the final velocity (0 m/s when the car stops), and t is the time. Participants clarify that the distance (Δx) is already provided, emphasizing the need to apply the equation correctly to find the time.

not sure I understand. Are you saying you do not know how to determine Δx? It is given.Akar said:I'm thinking about finding the Δx
Aren't you given the Δx? How far did the car drive until it stopped?Akar said:Homework Statement
A man was driving a car at 78 km/h, he saw a deer at the distance of 101m, how much time is needed so that the car slows down after it drove 99m and stops.
