5. Three objects are in harmonic motion modeled by the following curves: y1 = 10 sin (3t - ) y2 = 10 sin (3t - y3 = 10 sin( 3t + 23TT 6 (a) Find the amplitude, period, phase, and horizontal shift of the curve y1 . (b) Find the phase difference between the curves y1 and y2. Are the two curves in phase? (c) Find the phase difference between the curves y1 and y3. Are the two curves in phase? hour ed eesmargind all engood fei oldierv Jaour . Jeco L.8 - 0.5 = (3)0 relacall . to borroq ada bait (s)
