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)?

Answer Details

To find the acceleration between two points on a velocity-time graph, we need to calculate the slope of the line connecting the two points. In this case, we have two points: (10s, 15 ms⁻¹) and (20 s, 35 ms⁻¹).
The change in velocity between the two points is:
35 ms⁻¹ - 15 ms⁻¹ = 20 ms⁻¹
The change in time between the two points is:
20 s - 10 s = 10 s
Therefore, the acceleration is:
(change in velocity) / (change in time) = 20 ms⁻¹ / 10 s = 2 ms⁻²
So the answer is 2.00 ms⁻².
