    Answer:

    1.6875 m

    Explanation:

    Here, we are given that,

    • Initial velocity (u) = 0 (as it starts from rest)
    • Acceleration (a) = 1.5 m/s²
    • Time taken (t) = 1.5 s

    Then,

    • Distance (s) = ?

    By using the second equation of motion,

    s = ut + ½at²

    • s is distance
    • u is initial velocity
    • t is time
    • a is acceleration

    ⇒ s = 0(1.5) + ½ × 1.5 × (1.5)²

    ⇒ s = ½ × 1.5 × 2.25

    ⇒ s = ½ × 1.5 × 2.25

    ⇒ s = ½ × 3.375

    s = 1.6875 m

    Distance travelled by it is 1.6875 m.
