Answer:
The acceleration is

Step-by-step explanation:
Use the equation of motion,

where u=0m/s is the initial speed, v=9m/s is the final speed and t=2 seconds is the time.
We substitute the values into the equation and solve for the acceleration, a

This means that;

Divide both sides by 2 to get:


The pattern is subtracting 9
Answer:
I'm pretty positive its (0, 0)
Answer: 0.70
