Question

Find the maximum transverse velocity and acceleration of particles in the wire.

Open in App
Solution

Let the wave have the form y=Asin(kx)cos(ωt)
Thus transverse velocity=dydt=Aωsin(kx)sin(ωt)
Thus maximum transverse velocity=Aω=0.3cm×2πν
=0.003×2π×60=1.13m/s
Acceleration of particle is given by d2ydt2=Aω2sin(kx)cos(ωt)
Thus maximum transverse acceleration =Aω2=426.4m/s2
