Two simple harmonic motions are represented by the equation y_1 = 3(sqrt(3) cos 3 pi t + sin 3 pi t) and y_2 = 6 sin (6 pi t + pi//6)

Answer»

The ratio `A_1//A_2` of their amplitude is 1/2
The ratio `A_1//A_2` of their MAXIMUM velocities is `1//2`
The ratio `v_1//v_2` of their maximum velocities is 1/2
The ratio `v_1//v_2` of their maximum velocities is 2
