Correct option is
B
-5 m/s
2
average acceleration a=
t
v

eq(1)..
intial velocity is the slop of the graph in between the 0 to 2sec
v
1
=
2
40
=20ms
−1
final velocity os the slop of the graph in between the 6-8sec
v
2
=−
2
40
=−20ms
−1
total time is 8sec.
put v_{1}and v_{2} in eq(1)
a=
8
−20−20
=
8
−40
=−5ms
−2
Hence the answer is B option.
