276 Linear Momentum and Collisions P9.60 (a) The initial momentum of the system is zero, which remains constant throughout the motion. Therefore, when m 1 leaves the wedge, we must have mv 21 0 wedge block += or 3 00 0 500 4 00 0 .. . kg kg m s wedge bg b g b g v ++ = so v wedge ms =− 0667 . (b) Using conservation of energy for the block-wedge- Earth system as the block slides down the smooth (frictionless) wedge, we have v = 4.00 m/s block v wedge +x FIG.
