b) Calculate the momentum pp of block (P) before collision. c) Calculate the total momentum of the system of blocks pbefore before collision. After collision, it is seen that block (P) bounces back to the right with a speed v'p = 2m.s'. (S) (P) d) Knowing that the momentum of the system is conserved, determine the magnitude and the direction of the new velocity v's of block (S) after collision. Page 7 of 9
