Hi! If anyone could help me with this problem I'd be deeply appreciative:(adsbygoogle = window.adsbygoogle || []).push({});

Speed of Propagation vs. Particle Speed.The equationy(x,t)=A cos2(pi)f (x/v - t)may be written asy(x,t)= A cos[(2(pi)/lamda)(x-vt)]

a) Use the last expression fory(x,t)to find an expression for the transverse velocityv_yof a particle in the string of which the wave travels.

b) Find the maximum speed of a particle of the string?

I really have no idea how I'm even meant to approach this problem... Anyone know how to figure it out?

Thanks!
