Given information
As per the given information ,
- Car Velocity =
- Time before the light turns red
- Distance to the intersection in
- Width of intersection is
- Car can accelerate from
to 
in 
- Deceleration of the car =
Step-by-step explanation
Step 1.
To Determine Should she stop the car or speed up to cross the intersection 
we will use Third equation of motion ,
Third equation of motion:
Where, 
is the final velocity, 
is the initial velocity, is the acceleration and 
is the displacement.
Second equation of motion:
Where, is the displacement, 
is the time, is the initial velocity and is the acceleration
