Let the initial velocity of the car be u.
Final velocity of the car (v) = 5.43 m/s
deceleration (a) = - 2.78 m/s^2
Time taken (t) = 2.26 s
Using the first equation of motion:
v = u + at
u = v - at

u = 5.43 + 6.28
u = 11.71 m/s
Let the car's displacement be x.
Using second equation of motion:


x = 26.4646 - 7.0995
x = 19.3651 meters
Hence, the displacement of the car is 19.36 meters
