What is the acceleration between two points on a velocity time graph which has coordinates
(10s, 15 ms-1)
and (20 s, 35 ms-1)?
  • A.
    1.7 ms-2
  • B.
    3.50 ms-2
  • C.
    1.00 ms-2
  • D.
    2.00 ms-2
Correct Answer: Option D
Explanation

Acceleration = (AV)/At = (V2) – U1)/t2 – t1 = (35 – 15)/20 – 10 = (20)/10 = 2m5-2
