    Answer:

    The magnitude of the final velocity is 14.14 m/s

    Explanation:

    The horizontal component of the final velocity and vertical component of the final velocity, forms a perpendicular vector. To determine the magnitude of the final velocity, we sum the two vectors.

    To add two perpendicular vector, Pythagoras principle is used.

    [tex]V^2 = V_x^2 +V_y^2\\\\V = \sqrt{V_x^2 +V_y^2}\\\\V = \sqrt{(10)^2 +(-10)^2} =14.14 m/s[/tex]

    The magnitude of the final velocity is 14.14 m/s
