Question
A car moves at $75 \mathrm{~km} / \mathrm{h}$; its mass, including people, is $3200 \mathrm{~kg} .$ How much kinetic energy does the car have?
Step 1
We need to convert this to meters per second for our calculations. We do this by multiplying by $\frac{1000}{3600}$, which gives us: \[75 \mathrm{~km/h} = 75 \times \frac{1000}{3600} \mathrm{~m/s} = 20.83 \mathrm{~m/s}\] Show more…
