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)?
- 1.7 ms-2
- 3.50 ms-2
- 1.00 ms-2
-
2.00 ms-2
The correct answer is: D
Explanation
Acceleration = \(\frac{ΞV}{Ξt}\)
= \(\frac{V - U}{t_2 - t_1}\)
= \(\frac{35 - 15}{20 - 10}\)
= \(\frac{20}{10}\)
= 2ms\(^-2\)
