QUESTION 8

Convert [tex]30 \, \text{kmh}^{-1}[/tex] to [tex]\text{ms}^{-1}[/tex].

Sagot :

To convert a speed from kilometers per hour (km/h) to meters per second (m/s), you need to use the appropriate conversion factor between these two units.

Here’s the step-by-step process:

1. Understand the conversion factor:
- The conversion factor from kilometers per hour to meters per second is [tex]\(1 \, \text{km/h} = 0.27778 \, \text{m/s}\)[/tex].

2. Given speed:
- The given speed is [tex]\(30 \, \text{km/h}\)[/tex].

3. Multiply the given speed by the conversion factor:
- To convert [tex]\(30 \, \text{km/h}\)[/tex] to meters per second, you multiply it by the conversion factor [tex]\(0.27778 \, \text{m/s per km/h}\)[/tex].

[tex]\[ 30 \, \text{km/h} \times 0.27778 \, \text{m/s per km/h} = 8.3334 \, \text{m/s} \][/tex]

4. Conclusion:
- Therefore, [tex]\(30 \, \text{km/h}\)[/tex] is equivalent to [tex]\(8.3334 \, \text{m/s}\)[/tex].

Thus, the speed of [tex]\(30 \, \text{km/h}\)[/tex] converts to [tex]\(8.3334 \, \text{m/s}\)[/tex].
