Explanation:
It is given that,
Current carried in the conductor, I = 14.7 A (+x axis)
The magnetic force per unit length on the conductor, 
(-y axis)
The magnetic force is given by :
B = 0.0085 T
According to right hand rule, the direction of magnetic force can be calculated. So, the direction of magnetic field is along +z axis. Hence, this is the required solution.
In case they get affected by it
Answer:
The car is decelerating and its acceleration is negative.
Explanation:
First thing to consider. The car traveling direction is not important to answer the question.
Second, there are two affirmations on each sentence. So, lets take definitions:
Deceleration: Reducing the acceleration, from one value to another. No matter if the acceleration for the moment is positive or negative.
Acceleration negative: the driver is applying a force to make speed=0, the sign of this force must negative in order for the car to stop, other way it will go faster. Acceleration is the change rate of speed, if the speed is going down, the total acceleration until cars stops must be negative.
