If you are looking for the strenght of the electric field, then what you need to do is the following calculation:
E=F/q, and F=ma,
thus E=(ma)/q=(m· 2· x)/(t 2· q) = [(9.11×10-31kg)·2·(4.5m)] / [(3×10-6s)2(1.6×10-19C )]= 5.69 N/C
That is the strenght. Now that you know that the force is up and that the electron is negative then the projectile motion principles must be used

Answer:
Mr. Jones fills the cup 6 times with fertilizer.
Step-by-step explanation:
The capacity of the measuring cup = 1/8 cup
The total quantity of the fertilizer = 3/4 cup
Noe, as we know
total measure fertilizer = The capacity of the cup X number of times it takes.
So, 
or, here 
So, Mr. Jones fills the cup 6 times with fertilizer.
<span>x=y+2
2y=x-1
substitute </span>x=y+2 into 2y=x-1
2y=x-1
2y=y+2 -1
2y - y = 1
y = 1
<span>x=y+2
</span><span>x=1+2
x=3
answer
x = 3 and y = 1</span>
