Question

answer .. this please it's urgent ​

Answer 1

Explanation:

ii)

acceleration = ∆v/∆t = (8 - 0)/(2 - 0) = 4m/s^2

Retardation = -(∆v/∆t) = -(0 - 8)/(10 - 6) = 2m/s^2

【∆v = v(f) - v(i) ∆t = t(f) - t(i) 】

iii) During 2- 6 seconds body is moving with constant velocity.

iv)

Distance covered = Area made by v-t graph

Distance travelled = 1/2 × (10 + 4) × 8

= 4 × 14 = 96m

【AREA OF TRAPEZIUM = 1/2 × (SUM OF PARALLEL SIDES) × HEIGHT 】
