B. The velocity of the particle with respect to the acceleration is √x + 4.
Velocity is the rate of change of displacement with time.
The velocity of the particle with respect to the acceleration of the particle is calculated as follows;
vf = v₀ + at
where;
vf(x) = 2 + (√x + 2)
vf(x) = √x + 2 + 2
vf(x) = √x + 4
