The vibratory strut 1, fixed on two flat springs 2 and 3, performs translational motion according to the law XA = 0.16 sin 50? T, yA = 0.12 sin 50? T, where xA and yA are in cm. Determine the velocity in cm / From the point B to the vibratory carrier at time t = 1 s, if AB = 100 cm. (Response 31,4)
