Question
What is the velocity of the object? (Given a position-time graph with points (0,4) and (8,20))
Correct Answer
Option A is the correct answer.
Detailed Explanation
Velocity is the slope of the position-time graph. Using points (0,4) and (8,20), slope = (20-4)/(8-0) = 16/8 = 2 m/s.
Hint
Velocity = Δx/Δt.
