Question : A particle moving in a straight line and passes through a point 𝑂 with a velocity of 6𝑚𝑠−1 .The particle moves with a constant retardation of 2𝑚𝑠 −2 for 4 𝑠 and there after moves with a constant velocity. How long after leaving 𝑂 does the particle return to 𝑂

(A) 3𝑠

(B) 8𝑠

(D) 8 𝑚

Answer : option (B)

Solution :

A particle moving in a straight line and passes through a point 𝑂 with a velocity of 6𝑚𝑠−1 .The particle moves with a constant retardation of 2𝑚𝑠 −2 for 4 𝑠 and there after moves with a constant velocity. How long after leaving 𝑂 does the particle return to 𝑂
