Waves and its Characteristics: Practice Problem & Solution

Solution Explained:

To solve this problem, we apply the core principles of Waves and its Characteristics. Understanding the underlying formula is key to arriving at the correct answer below:

Comparing with $y = a \sin(\omega t - kx)$, we get $\omega = 100$ and $k = 1/10$. Velocity $v = \frac{\omega}{k} = \frac{100}{1/10} = 1000 \text{ m/s}$.
