Answer

A, C, D Explanation 1. Identify vector property Velocity is a vector quantity, meaning it has both magnitude and direction. Thus, statement A is correct. 2. Analyze slope of acceleration vs. time graph The slope of an acceleration vs. time graph represents jerk, not velocity. Thus, statement B is incorrect. 3. Check units of measurement Velocity can be measured in meters per second (m/s), which is a standard unit for velocity. Thus, statement C is correct. 4. Define velocity formula Velocity is defined as the change in displacement divided by the change in time, aligning with the formula v = \frac{\Delta x}{\Delta t}. Thus, statement D is correct.
