0.2000 kg of water at 20.00°c is contained in a 0.1000-kg copper container. the container is shaken vigorously for 10.00 minutes to cause the temperature to rise to 22.00°c. calculate the work done on the system and the heat supplied to the system. the specific heat of copper is 385.0 j/kg and of water is 4200.0 j/kg

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.
