When the brakes of a certain car are applied, a deceleration of [tex]6.0 \, \text{m/s}^2[/tex] is produced. How much time will it take to bring the car to a halt from an initial speed of [tex]110 \, \text{km/hr}[/tex]?

Use the formula:
V = V o ​ + a t 15.27 = 30.55 − 6 t 6 t = 30.55 − 15.27 6 t = 15.28 t = 6 15.28 ​ = 2.54 s

To stop the car from an initial speed of 110 km/h, which converts to approximately 30.56 m/s, it will take around 5.09 seconds given a deceleration of 6.0 m/s². The time is calculated using the formula for deceleration. This result indicates how long it takes for the car to halt when braking is applied.
