Question
The diagram below presents the position and elapsed time of a motorbike that starts from rest and accelerates at a constant rate. What is the average velocity of the motorbike during first 5 s?
Correct Answer
Option C is the correct answer.
Detailed Explanation
Without the diagram, we assume typical: for constant acceleration from rest, average velocity = (initial + final)/2. If it covers 50m in 5s, average velocity = 50/5=10 m/s. This is a common result: v_avg = (0 + v_f)/2, and if v_f = 20 m/s after 5s, average = 10 m/s.
Hint
Average velocity = total displacement / total time.
