Question
What is the acceleration of the object between 2 s and 6 s? (Given a velocity-time graph with points: at t=2, v=4; at t=6, v=4, so constant velocity)
Correct Answer
Option A is the correct answer.
Detailed Explanation
From the graph, the velocity is constant at 4 m/s from t=2 to t=6. Constant velocity means zero acceleration.
Hint
Acceleration is the slope of the velocity-time graph.
