Answer:

hii

here is ur answer!

V(velocity)=d(s)/dt means differentiation of displacement with respect to time

so V dt =d(s)

integration on both sides

S= integration of V with respect to t(time)

so that means s is the area under graph of velocity and time

In time 1-2sec displacement =area under graph

=area of rectangle

= base ×height =2×2=4

In time 2-3 sec diplacement = area of trapizium

=0.5×1×(2+6)=4

in time 3-4 displacement= area of triangle

=0.5×1×6=3

In time 4-5 displacement=area of triangle

= -0.5×1×6= -3

In time 5-6 diplacement = -1×6= -6

In time 6-8 diplacement = 2×4=8

TOTAL displacement =4+4+3-3-6+8=10m

Answer:10m
