Answer:
If the velocity time graph is given, in order get the displacement we need to find the area under velocity - time curve.
Area above time axis (x - axis) is taken to be +ve displacement
Area below time axis (x - axis) is taken to be -ve displacement
Total displacement = Area of OABC + CDEF + FGHI
Area of
OABC = 2 x (+4) = +8m
CDEF = 6 x (-2) = -12m
FGHI = 2 x (+6) = +12m
Total displacement = (+8 -12 +12) = +8m
The displacement is +8m in 10s
