    P = m * v

    v = {3i - 4j} = square root (3^2 + 4^2) = 5

    P = 20 * 5

    P = 100 kg m/s

    Magnitude:

    √ (3² + 4²) = √ (9 + 16) = √25 = 5

    Momentum = (mass) x (velocity) = (20kg x 5m/s) = 100 kg-m/s

    Direction:

    3i - 4j is in the direction tan⁻¹ (-4/3) = 53.1 south of east.
