1. The problem statement, all variables and given/known data A boat is on a quiet lake 200 m from a paddle wheel that creates waves which pass the boat every 1.8 s with an amplitude of 3 cm. A) If the wave velocity for water waves is 1.5 m/s, what is the wavelength? B) Write an equation for the displacement of the water as a function of position and time C)What is the amplitude of the wave if the boat is moved 60 m closer to the paddle wheel? 2. Relevant equations v = lambda/T D = Asin(kx - wt) k = 2pi/lambda v = w/k 3. The attempt at a solution A) I dont think this question is worded very clearly but I am assuming they mean that the period is 1.8 s if that is true then v= lambda/T so lambda = Tv = 1.8s * 1.5 m/s = 2.7 m B) D = Asin(kx-wt) k = 2pi/lambda = 2pi/2.7 = 2.32 v = w/k so w = vk = 1.5 * 2.32 = 3.48 a is given as .03 m so D = .03sin(2.32x-3.48t) C) the wave is going 1.5 m/s so it goes 60 m in 60/1.5 = 40 s D = .03sin(2.32*60 - 3.48 * 40) = .03sin(0) = 0 the water is flat at that point I am not confident at all that I did this right. please help?
