Please help!
Having a little difficulty with a homework question and concept
y = 2.28sin(0.0276pi x + 2.42pi t)
Find the amplitude, wavelength, frequency, speed and maximum transverse speed.
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) ?
