18. They pass each other at time t , at x x x m 12 1 2 == where xx t t mm 11 2 2 =+ cos( ) cos( ). ω φ and From this, we conclude that cos( ) cos( ) tt += 1 2 , and therefore that the phases (the arguments of the cosines) are either both equal to π /3 or one is π /3 while the other is – π /3. Also at this instant, we have v 1 = – v 2 0 where vx t t =− + + sin( ) sin( ). and This leads to sin( t + 1 ) = – sin( t +
