Please help!!! Having a little difficulty with a homework question and concept 1. The problem statement, all variables and given/known data y = 2.28sin(0.0276pi x + 2.42pi t) Find the amplitude, wavelength, frequency, speed and maximum transverse speed. 3. The attempt at a solution Definitely correct answers A = 2.28cm Wavelength = 72.46 cm Frequency = 1.21 Hz Questionable answers Speed = 87.68 cm/s Max transverse speed = ?????? Reasoning The speed should be w/k which would give 2.42pi/0.0276pi = 87.68 cm/s The max transverse velocity though....would that be when the trig function of cos is equal to 1 in this equation u = -wAcos(kx-wt) ????
