Question 23

Motion

What is the acceleration of a particle whose motion is graphically displayed in the above figure?

Diagram for this question
  1. A.0.67 m s−2
  2. B.0.83 m s−2
  3. C.0.87 m s−2
  4. D.92 m s−2
  5. E.2.0 m s−2
Show the answer and explanation

Answer: A (0.67 m s−2)

Explanation

Acceleration is the slope of the velocity–time graph: the velocity rises from 2 to 6 m s−1 in 6 s, so a = 4/6 ≈ 0.67 m s−2.
