How much kinetic energy does a 3kg soccer ball have while moving at $20 \mathrm {~m} / \mathrm { s }$ toward your opponents' goal?

Question

Quizplus · Accepted Answer

The kinetic energy (KE) of an object can be calculated using the formula $KE = \frac{1}{2}mv^2$, where $m$ is the mass of the object and $v$ is its velocity. Substituting the given values, $m = 3 \, \text{kg}$ and $v = 20 \, \text{m/s}$, we get $KE = \frac{1}{2} \times 3 \times (20)^2 = \frac{1}{2} \times 3 \times 400 = 1.5 \times 400 = 600 \, \text{Joules}$.
