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

Answer»

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
