Acar traveling at a speed of 24 m/s comes to a stop at a red light. how much time will it take for the car to stop if its acceleration is –8.0 m/s2? 3 s

The time it takes for a certain object to stop given its initial velocity is calculated by dividing the velocity by the deceleration given. That is,

                            Time = initial velocity / deceleration

                             Time = (24 m/s) / (8 m/s2)

The equation above will give us an answer of 3 s.

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.
