If the swimmer starts at rest, slides without friction, and descends through a vertical height of 2.66 m , what is her speed at the bottom of the slide?

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.

Scientific models are based on current knowledge, which can limit their effectiveness when new discoveries are made.
