    Acceleration is defined as the change in velocity per unit of time

    Acceleration (a) = ΔV/t

    V = Velocity t = time

    ΔV = V₂ - V₁ t = 11s

    V₁ = 44m/s

    V₂ = 66m/s

    ΔV = 66 - 44

    = 22m/s

    Acceleration (a) = 22/11

    = 2m/s²

    Displacement (d) : Displacement equals the original velocity multiplied by time plus one half the acceleration multiplied by the square of time.

    d = v₀ + 1/2*at²

    v₀ = 44m/s

    a = 2m/s

    t = 11s

    d = 44 + 1/2 * (2 x 11²)

    = 44 + 121

    d = 165m
