HelpI I don't know why I keep getting a wrong!

I tried:

0.14*61 = 8.5

61/0.14 = 437

0.14*0.85= 0.12

and they are all wrong

A sinusoidal wave on a string is described by the wave function y = .14 sin (.85x - 61t) where x and y are in meters and f is in seconds. The mass per unit length of this string is 12. g/m. Determine the speed of the wave. Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully, m/s Determine the wavelength, m Determine the frequency. 9.7 Hz Determine the power transmitted by the wave.

Explanation / Answer

a ) 61/0.85 = 71.765 m/s

b) 2*pi/0.85 = 7.39 m

d) 0.5*0.012*61^2*0.14^2*71.765 = 31.4
