The second friend is correct.

Work Step by Step

For very slow projectiles, the dropping distance is large compared to the horizontal range, and the effect is noticeable. For high speed projectiles, the same vertical drop occurs, but the horizontal distance is so large that the curve is less noticeable. This is discussed on pages 185-186, and shown in Figure 10.8.
