Question

A driver applies the brake and his car goes from 15m/s² to a halt within 5seconds.how much distance did it travel before coming to a halt ​

Answer 1

To find the distance the car traveled before coming to a halt, we can use the formula:

distance = initial velocity x time + (1/2) x acceleration x time^2

In this case, initial velocity is 15m/s², time is 5 seconds, and acceleration is -15m/s² (negative because the car is decelerating to a stop).

So, distance = 15m/s² x 5 seconds + (1/2) x -15m/s² x (5 seconds)^2

The distance the car traveled before coming to a halt is approximately 168.75 meters.
