9.8m/s

Answer

To solve the problem step by step, we need to clarify the context of the question. It seems like we are multiplying several velocities given in meters per second (m/s). Here’s how we can approach this:

### Step-by-Step Solution:

1. **Identify the quantities**: We have four velocities given:
- \( v_1 = 9.8 \, \text{m/s} \)
- \( v_2 = 10 \, \text{m/s} \)
- \( v_3 = 5.8 \, \text{m/s} \)
- \( v_4 = 17.3 \, \text{m/s} \)

2. **Multiply the velocities**: Since we are multiplying these velocities together, we can express this as:
\[ v_{\text{total}} = v_1 \times v_2 \times v_3 \times v_4 \]

3. **Perform the multiplication**:
\[ v_{\text{total}} = 9.8 \times 10 \times 5.8 \times 17.3 \]

4. **Calculate step by step**:
- First, multiply \( 9.8 \times 10 = 98 \)
- Next, multiply \( 98 \times 5.8 = 568.4 \)
- Finally, multiply \( 568.4 \times 17.3 = 9833.32 \)

5. **Combine the units**: Since we are multiplying velocities (m/s), the resulting unit will be:
\[ \text{m/s} \times \text{m/s} \times \text{m/s} \times \text{m/s} = \text{m}^4/\text{s}^4 \]

6. **Final Result**: The final result of the multiplication is:
\[ v_{\text{total}} = 9833.32 \, \text{m}^4/\text{s}^4 \]
