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.

Δx = 1/2 (vi + vf) * tThe Attempt at a Solution
I'm thinking about finding the Δx
Constant acceleration is the rate of change of velocity over time that remains steady. This means that the velocity of an object increases by the same amount in each unit of time.
To calculate time with constant acceleration, you can use the formula t = (vf - vi)/a, where t is time, vf is final velocity, vi is initial velocity, and a is acceleration.
Yes, constant acceleration can be negative. This indicates that the object is decelerating, or slowing down, at a constant rate.
Constant acceleration causes an object's velocity to change at a constant rate, resulting in a linear change in its position over time. This means that the object's motion is uniform and predictable.
Some real-life examples of constant acceleration include a car gradually speeding up or slowing down on a straight road, a roller coaster going down a hill, and a ball falling due to gravity.
