The man of mass m1 = 82 kg and the woman of mass m2 = 80 kg are standing on opposite ends of the platform of mass m0 = 103 kg which moves with negligible friction and is initially at rest with s = 0. the man and woman begin to approach each other. find the displacement s of the platform when the two meet if the displacement x1 of the man relative to the platform is 9 m. the length l of the platform is 15.5 m.
