Would you please solve it real quick, that will be helpful and appreciated. Thank you. I will give you a good feedback too.

14) A transverse wave is traveling to the right down a string of mass 0.050 kg and length 30 m. The string's tension is 90 N. A picture of the wave is taken at the instant shown at t = 0 s. (a) What is the speed of the wave? 0)) What is the wavelength? (c) What is the equation of motion of the wave? (That is. what is the equation describing the graph below?) (d) On the graph indicate the direction that the piece of string located at point P is moving. yhm .l' 'llrn
