The horizontal distance traveled will be

#### Explanation:

As for all projectile motion questions, we can treat the horizontal and vertical direction independently. If we ignore air resistance, the horizontal velocity will remain constant at

We need to calculate the time taken for the ball to fall. The initial velocity

The horizontal distance traveled in this time will be
