A5.0 n block rests on an incline 3 m above the bottom of the incline, as shown. the block is then hit by a hammer so that it has a speed of 1.0 m/s down the incline after being hit. if the incline is 5 m long, and the coefficient of kinetic friction between the block and the incline is μk = 0.75, what is the block's speed when it reaches the bottom of the incline

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.
