Q 11-14-007NEETJEE MainMedium
For the wave $y = 0.1\sin(100\pi t - 2\pi x)$ (SI units), the maximum speed of a particle of the medium is
Answer: (C) $10\pi$ m/s
$v_{p,max} = A\omega = 0.1 \times 100\pi = 10\pi \approx 31.4$ m/s. (The wave speed is $\omega/k = 50$ m/s, which is a different quantity.)
