Ronnie kicks a playground ball with an initial velocity of 16 m/s at an angle of 40 degrees relative to the ground. What is the approximate horizontal component of the initial velocity?

The horizontal component is found by multiplying the initial speed by the cosine of the angle: 16 cos(40°) ≈ 16 × 0.766 ≈ 12.3 m/s. So the approximate horizontal component is 12.3 m/s, choice A.
