a 0.5 kg drone flies at a speed of 20 m/s. how much kinetic energy does the drone have? remember : $e_{k}=\frac{1}{2}mv^{2}$ $e_{k}=? j$
Answer
Explanation:
Step1: Identify values
$m = 0.5\ kg$, $v=20\ m/s$
Step2: Substitute into formula
$E_{K}=\frac{1}{2}\times0.5\times(20)^{2}$ $E_{K}=\frac{1}{2}\times0.5\times400$ $E_{K}=100$
Answer:
$100$
