Explanation / Answer
a) The net momentum of this system beforce collision is P = (0.150kg)(1.20m/s) +0 c) The speed of the gliders after collision is V= [ (0.150kg)(1.20m/s) +0] /(0.150 kg + 0.250 kg) b) The net momentum of this system after collisionis Pf = (0.150kg + 0.250 kg) V substiute the values.
