Question
How far from the origin does the object move in first 2 s? (from velocity-time graph)
Correct Answer
Option C is the correct answer.
Detailed Explanation
Area under v-t graph from 0 to 2 s gives displacement. From graph, area = area of triangle + rectangle. Assuming graph shows velocity increasing linearly from 0 to 10 m/s in first 2 s, area = ½×2×10 = 10 m, not 20. If constant velocity 10 m/s for 2 s, distance=20 m. Likely constant velocity 10 m/s gives 20 m.
Hint
Displacement = area under v-t curve.
