Question
Compare the kinetic energy of a 20,000-kg truck moving at 110 km/h with that of an 80.0-kg astronaut in orbit moving at 27,500 km/h.
Step 1
Step 1: First, we need to understand the formula for kinetic energy, which is given by $\frac{1}{2}mv^2$, where $m$ is the mass of the object and $v$ is its velocity. Show more…

Compare the kinetic energy of a 20,000 kg truck moving at 110 km/h with that of an 80 kg astronaut in orbit moving at 27,500 km/h.
Which has more kinetic energy, a 1400 $\mathrm{kg}$ car moving at 115 $\mathrm{km} / \mathrm{h}$ or a $12,000 \mathrm{kg}$ truck moving at 38 $\mathrm{km} / \mathrm{h}$ ?
