Answer:
Explanation:
To determine the displacement under the velocity-time graph, we explore the area of the:
(1) region of acceleration
(2) region of constant velocity
(3) area of region of deceleration
so to couple this up, we explore the area of a trapezium
height = 10
a = length BC = 8 - 2 = 6
b = 10
Area of a trapezium = 1/2(a + b)*h = 1/2(6 + 10)*10 =8*10 = 80m
The displacement = 80m
