To solve this problem, we need to calculate the initial horizontal velocity of the football. 

Given:
- The angle of projection, \( \theta = 37.0^\circ \)
- The initial velocity of the football, \( v = 25.0 \, \text{m/s} \)

The initial horizontal velocity component, \( v_x \), can be calculated using the formula:
\[
v_x = v \cdot \cos(\theta)
\]

### Calculation
1. Substitute \( v = 25.0 \, \text{m/s} \) and \( \theta = 37.0^\circ \) into the formula.
2. Use the cosine value for \( 37.0^\circ \), which is approximately \( \cos(37.0^\circ) \approx 0.7986 \).

\[
v_x = 25.0 \, \text{m/s} \times 0.7986
\]
\[
v_x \approx 19.965 \, \text{m/s}
\]

### Answer
The initial horizontal velocity of the football is approximately:
\[
v_x \approx 19.97 \, \text{m/s}
\]

5. How does the initial velocity affect the maximum height the football can reach?

**Tip:** Remember, for any projectile motion, the horizontal velocity remains constant throughout the flight (assuming no air resistance).

A punter kicks a football at an angle of 37.0° to the horizontal ground. The football has an initial velocity of 25.0 m/s. Calculate the initial horizontal velocity of the football.
