Question 4

Motion

What is the acceleration between two points on a velocity-time graph which has coordinates (10s, 15 ms−1) and (20 s, 35 m s−1)?

  1. A.1.75 ms−2
  2. B.3.50 ms−2
  3. C.1.00 ms−2
  4. D.2.00 ms−2
Show the answer and explanation

Answer: D (2.00 ms−2)

Explanation

Acceleration is the slope of the velocity-time graph: (35 − 15) ÷ (20 − 10) = 20 ÷ 10 = 2.00 m s−2.
