Let's analyze the problem presented in the image.

### Problem: 
A ball is thrown upwards with an initial velocity of 40 m/s. The question asks for the velocity of the ball after 2 seconds.

### Key Concepts:
1. **Initial Velocity (\(u\))**: 40 m/s (upwards).
2. **Acceleration due to gravity (\(g\))**: \( -9.8 \, \text{m/s}^2 \) (negative since it acts downward).
3. **Time (\(t\))**: 2 seconds.

### Using the kinematic equation for velocity:
\[
v = u + at
\]
Where:
- \(v\) is the velocity after time \(t\),
- \(u\) is the initial velocity,
- \(a\) is the acceleration (here, gravity),
- \(t\) is the time.

Substitute the known values:
\[
v = 40 \, \text{m/s} + (-9.8 \, \text{m/s}^2)(2 \, \text{seconds})
\]
\[
v = 40 \, \text{m/s} - 19.6 \, \text{m/s}
\]
\[
v = 20.4 \, \text{m/s}
\]

Since the velocity is still positive, the ball is still traveling **upward** after 2 seconds with a velocity of approximately **20.4 m/s**.

Therefore, the closest correct answer from the choices is:
**"20 m/s traveling upward."**
