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 acceleration of the motorbike? (positions: 0s:0m, 1s:2m, 2s:8m, 3s:18m, 4s:32m)
Options
A 0 m/s²
B 2 m/s²
C 4 m/s²
Correct Answer
D 6 m/s²
Correct Answer

Option C is the correct answer.

Detailed Explanation

Using s = ½at², at t=2 s, s=8 m → 8 = ½a×4 → 8 = 2a → a = 4 m/s². Check at t=4 s: ½×4×16 = 32 m, matches.

Hint

s = ½at² from rest.
