    Answer

    C.) 1.0 x 10^2 Newton's

    Explanation

    The Newton's second law of motion states that, the rate of change of momentum is proportional to the force producing it.

    ∴ F = (mv - mu) / t

    Ft = mv - mu.

    The quantity Ft is called the impulse.

    Ft = 0.30 Newton seconds

    but t = 3.0 x 10⁻³ seconds

    Ft = 0.30 Ns

    F * 3.0 x 10⁻³ = 0.30 Ns

    F = 0.30 / (3.0 x 10⁻³)

    = 100 N

    Answer = C.) 1.0 x 10^2 Newton's
