# Problem: Which has zero acceleration? An object A) moving at constant velocity. B) at rest. C) in mechanical equilibrium. D) all of the above E) none of the above

###### FREE Expert Solution

Acceleration is the rate of change of velocity:

$\overline{){\mathbf{a}}{\mathbf{=}}\frac{\mathbf{∆}\mathbf{v}}{\mathbf{t}}}$

When an object is at a constant velocity, Δv = 0.
