5. To guarantee that this car can break the latest rally records, the owner decided to make simple
calculations to check the time needed to drive the racing distance, the equation he remembers
from the old school days in the physics course when he was a student is:
Xf = Xi + V* t+0.5 a*t
Where: xf, xi are the final and initial positions relatively, v is the velocity, a is the acceleration and
t is the time. Prove to the owner that the equation he will use is dimensionally incorrect.
