Answer 1

Answer:

it's answer is so simple try to do it yourself and have a b c d

Answer 2

Answer:

Option(3) = 10m/s

Explanation:

Area under a-t graph gives CHANGE IN VELOCITY.

For the first triangle,

1/2*6*2 = v(6) - v(0)

6 = v(6) - 10

v(6) = 16m/s

For the second triangle,

1/2*(-6)*2 = v(8) - v(6)

-6 = v(8) - 16

v(8) = 10m/s
