Theanswer has been derived below though you should know that kinetic energy of a particle performing SHM is maximum when x=0

$Kinetic energy=\frac{kA^{2}}{2}-\frac{kx^{2}}{2} Maximum KE =\frac{kA^{2}}{2} =\frac{mw^{2}A^{2}}{2} =\frac{\rho Vw^{2}A^{2}}{2} =\frac{\rho V4 \pi ^{2}n^{2}A^ {2}}{2} (k=mw^{2} \boldsymbol{and} w. =2 \pi n)$

displacement associated with three dimensional wave is given by sai x y is equal to 1 + 1 by 2 x + root 3 by 2 k x minus omega t show that the wave propagates along a direction making an angle 60 degree with the x-axis
