Question

Find the total displacement of the body from the following graph:-

Answer 1

The given graph is velocity time graph so its area will give displacement of object.
from 0 to 2 ,
displacement =1/2 × 2 ×5 =5 m
from 2 to 6 s,
displacement = 4× 5 = 20 m
from6 to 8s,
displacement =2×5 + 1/2×2×5 =15m
Since area from 8 to 10s is same so,
displacement = 15m
Total displacement = 5+20+15+15 =55m

Answer 2

Answer:

55 meter

Explanation:

The given graph is velocity time graph so its area will give displacement of object.

from 0 to 2 sec ,

displacement =1/2 x 2 x 5 =5 min

from 2 to 6 sec,

displacement = 4 x 5 = 20 min

from 6 to 8 sec,

displacement =2 x 5 + 1/2 x 2 x 5 =15 min

Since area from 8 to 10 sec is same so,

displacement = 15 min

Total displacement = 5+20+15+15 =55 min
