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? (Positions: at t=0, x=0; t=1, x=2; t=2, x=8; t=3, x=18; t=4, x=32; t=5, x=50)
Correct Answer
Option C is the correct answer.
Detailed Explanation
Average velocity = total displacement / total time = (50 m - 0 m) / 5 s = 10 m/s.
Hint
Average velocity is displacement divided by time.
