    Answer:

    Vertical velocity   V_y = 10.89 \ m/s

    Horizontal velocity  V_x = 15.57 \ m/s

    Explanation:

    If a 1 -kg is thrown vertically with a velocity of 19  m/s at an angle of 35 °C from a height 1.94 m

    The vertical and horizontal component can be resolved as:

    V_y = Vsin \theta \\ \\ \\\\V_x = Vcos \theta

    For Vertical component :

    V_y = V sin \theta \\\\V_y = 19 * sin 35 \\ \\ V_y = 19* 0..5736 \\ \\ V_y = 10.89 \ m/s

    For horizontal velocity

    V_x = V cos \theta \\\\V_x = 19 * cos 35 \\ \\ V_x = 19* 0.8192 \\ \\ V_x = 15.57 \ m/s
