QUESTION:
If a Saturn V rocket with an Apollo spacecraft attached had a combined mass of \(2.9 \times {10^5}\;{\rm{kg}}\) and reached a speed of \(11.2\;{\rm{km/s}}\), how much kinetic energy would it then have?
ANSWER:Step 1 of 3
Given data:
The combine mass is \(m=2.9\times {{10}^{5}}\ \text{kg}\).
The velocity is \(v=11.2\ \text{km/s}=11.2\times 1000\ \text{m/s}=11200\ \text{m/s}\).
