D would be the answer because The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
85 N - 40 N = 45 N
And depending on direction the greater force is being pulled towards
The correct answer is

force per unit charge.
In fact, the electric field strength is defined as the electric force per unit charge experienced by a positive test charge located in the electric field. In formula:

where
E is the electric field strength
F is the electric force experienced by the charge
q is the positive test charge.
Answer: 160 m
Explanation: First find time or t using the formula for acceleration:
a = vf - vi / t
So t is equal to:
t = vf - vi / a
= 0 m/s - 20 m/s / -2.5 m/s²
= 8 s
To find the distance use the formula for velocity:
v = d / t
Derive for d:
d = v x t
= 20 m/s x 8 s
= 160 m
