12 m/s

The change in velocity is the final velocity minus the initial velocity, which is 12 m/s - 0 m/s = 12 m/s.

Misunderstanding Acceleration Calculation

Students often confuse the formula for acceleration, mistakenly using distance instead of change in velocity.

Remember that acceleration is defined as the change in velocity over time. Use the correct formula: acceleration = change in velocity / time taken.
