Answer the given question

Answer 1

Answer:

55m

Explanation:

Displacement = vt

That is... Area under graph

Area under

ABF = 5 m

BEIG = 40 m

CDE = 10 m

Net = 55m

Answer 2

Answer:

55m

Explanation:

The area under vt graph gives displacement.

1) Area of triangle (ABF) = 1/2 . b . h

= 1/2 . 2 . 5

= 5 m

2) Area of rectangle (BCGF) = L. B

= FG . CG

= (6-2) . 5 = 20 m

3) Area of rectangle (CGiE) = L . B

= (10 - 6) . 5 = 20 m

4) Area of triangle (ECD) = 1/2 . b . h

= 1/2 . (10 - 6) . (10 - 5)

= 1/2 . 4 . 5 = 10 m

Total displacement = 1 + 2 + 3 + 4

= 5 + 20 + 20 + 10 = 55 m
