Observe the following graph and calculate displacement of the object i

1.	Observe the following graph and calculate displacement of the object in 12 sec.
Answer» 1) Displacement (s) = Area of the graph = Area of ABDO rectangle + BDC triangle. 2) Area of the rectangle ABDO = 8 × 20 = 160. 3) Area of the triangle BDC =1/2 × 20 × (12 – 8) = 1/2 × 20 × 4 = 40. 4) Displacement (s) = 160 + 40 = 200 m. 5) Hence, displacement of the object in 12 sec. = 200 m.

Observe the following graph and calculate displacement of the object in 12 sec.

Answer»

1) Displacement (s) = Area of the graph = Area of ABDO rectangle + BDC triangle.

2) Area of the rectangle ABDO = 8 × 20 = 160.

3) Area of the triangle BDC =1/2 × 20 × (12 – 8)

= 1/2 × 20 × 4 = 40.

4) Displacement (s) = 160 + 40 = 200 m.

5) Hence, displacement of the object in 12 sec. = 200 m.
