JEE main - Physics

A transverse travelling wave represented by a equation: y = (1 cm) sin[2nx – 20πt]; where X is in meters and t is in seconds, is travelling on a string of mass per unit length 0.01 Kg/m. Find the kinetic energy (in mille joule) of a portion of the string of length equal to one wavelength. (Take : π² = 10)
