First we will use the concepts of motion kinetics for which the final speed is defined as shown below,

Here,
= Final velocity
= Initial velocity
a = Acceleration
s = Distance
Replacing,


Using the conservation of energy for kinetic energy we have,



Therefore the kinetic energy of the car is 31900J
Answer:
Technician B only is correct
Explanation:
Here we have that the multiple discharge ignition system is a system that fires the spark plug multiple times during each power stroke to provide ample spark to complete the ignition. Therefore, technician A is not correct.
The dual spark plug ignition system is a method if obtaining the ideal combustion and improved fuel consumption than a single spark plug ignition system.
Therefore, only technician B is correct.
Rocks, earth aging, fossils
