GB-29-06-001 · Acceleration

A vehicle accelerates uniformly from 8 m/s to 26 m/s in 10 s. Calculate its acceleration to 2 decimal places.

Velocity–Time Graphs: Acceleration Booklet p. 58
Method
The GRADIENT of a velocity–time graph represents ACCELERATION: a = (v − u) ÷ t
Worked Example (GB-29-06-001)
Booklet p. 58: Area under V–T graph = Distance (Area 1◯+Area 2◯+Area 3◯\text{Area }\textcircled{1} + \text{Area }\textcircled{2} + \text{Area }\textcircled{3}) · Gradient = Acceleration (y2−y1x2−x1\frac{y_2 - y_1}{x_2 - x_1})
1) (26 − 8) ÷ 10.
2) 1.80 m/s²
1.80 m/s²
