A student discovers an asteroid with a mass of 0.00018 earth masses orbiting the sun with an orbital radius of 2.44AU. How long would the asteroid take to orbit the sun?

The man of mass m1 and the woman of mass m2 are standing on opposite ends of the platform of mass m0 which moves with negligible friction and is initially at rest with s = 0. the man and woman begin to approach each other. derive an expression for the displacement s of the platform when the two meet in terms of the displacement x1 of the man relative to the platform.
