and after collision. Comment on this 0 Compare the kinetic energies of the system before outcome. Practice Exercises: 1) A car of mass m = 1200kg is moving along a horizontal road with a constant speed v = 15111.3". Calculate the ma nitude of the linear momentum of the car. 2) Two blocks (S) and (P) of respective masses ms = 5kg and mp = 2kg are moving towards each other with speeds vs = 4m.s'l and vi: = 3m.s'1 as shown below. (P) . VL- Take the direction to the right to be the positive direction. of block S before collision. a) Calculate the momentum s Page 6 of9
