rocket’s speed.
Measurements Easy
Problem
A rocket in low orbit travels at 27,000 km/h. Convert this speed to metres per second — the SI unit every other calculation will expect.
- Speed\( 27{,}000\ \mathrm{km/h} \)
- Kilometre\( 1\ \mathrm{km} = 1000\ \mathrm{m} \)
- Hour\( 1\ \mathrm{h} = 3600\ \mathrm{s} \)
- Answer inm/s
Hint: multiply by metres per kilometre, divide by seconds per hour — or use the shortcut: km/h \( \div\ 3.6 \) = m/s.
