What represents a case in which you are not accelerating?

Answer: dv/dt = 0

Explanation: Acceleration has to do with when you are changing velocity. since velocity is a speed and a direction you only accelerate when you change speed or change direction or change both in other words you are not accelerating when you are moving in a constant speed and at a specified direction. E. g driving Eastward at a constant speed of 24m/s, such scenario is a case of not accelerating that is acceleration is zero.
