reaction time of a driver to brake is 0,5s in that time the speed is constant

the speed of a car is constant when he decides to slow down and to stop with -6,0 m/s2, the initial speed is 50 km/h

Calculate the total stopping distance of the car

## Homework Equations

Ve= -6,0*t +13,89

t=2,3

xe=-6,0*(2,3)^2 +13,89*2,3

what did I do wrong?

## The Attempt at a Solution

the solution has to be 23,03 m but I can't solve it,
