    Explanation:

    Given that,

    The initial velocity of the object, u = -11.2 m/s (due west)

    Acceleration of the object, a=+2.78\ m/s^2 (due east)

    Time, t = 2.03 seconds

    We need to find the distance traveled by the object during this time. Let the distance covered is d. Using second equation of motion to find it as :

    d=ut+\dfrac{1}{2}at^2\\\\d=-11.2\times 2.03+\dfrac{1}{2}\times (2.78)\times (2.03)^2 \\\\d=-17.007\ m

    So, the object cover a distance of 17.007 meters in the westward direction.
