    Answer:

    Hello

    Step-by-step explanation:

    Given that the motion is in 1 Dimension and the body doesn’t change it’s direction (i.e. velocity is in the direction of acceleration), we have:

    s=u+a(2t−1)/2

    12 = u + a(2*2 – 1)/2

    => 12 = u + 3a/2

    => 2u + 3a = 24

    and

    20 = u + a(2*4 – 1)/2

    20 = u + 7a/2

    => 2u + 7a = 40

    From 1 and 2:

    a = 4

    u = 6

    Now, distance covered in 4s after 5th second = Distance covered in 9 seconds – distance covered in 5 seconds

    = 6*9 + 1/2 * 4 * 9 * 9 – (6 * 5 + 1/2 * 4 * 5 * 5)

    = 54 + 162 – (30 + 50)

    = 136 m
