Answer 1

1119 2 534't moss of portiere (m) = 29 j a speet (V.): Sico misec i oleg - mass of 2nd particle (m2) = 1 0 ) After collision speed of first portiere is 2 backwary Ø 2ind particle r2 is forwort virh. sso, For perfectly elastic collision, e=1 or Vitral V, +12=5160 -!! 999 ?? UI From Conservation of momentum, 3-mir, tm,v2 = miu 33-(2) vit va = (@115160 V2 - 2V1= 11.9 - 2 Now, from it x oil we get, t hey DOPO $ Y2 - 2V1 = 11:2 + Vi = 516 inih studija ! Iné 3V1 = 5:6 Vi = -516 = -1187 m/sec , That means our assume dirln after Collision is opposite * Vg = 5160 - Vi Va = 7.46 msee

(6) el relocity of ar particle is 1,87 m/sec (2) - Volody of 12 porticle is 7.46 misec (Ŝ If m₂ = 10 gm then vitr2 = 5.66 iso CODE and -mir,+ mare = moi mai 2 - 2V,+ 10 V2 = 1702 + ) Pingente + V + 2 = 11:2 12 V2 = 2204 = 22.4 - 1.86 m ic V = 1.86 misec 2 x le=5.60-12 = 3.74 m/sec 7 ans relocity of a gm particle is 3.74 m/stole " 10 gm u 1186 misce (C) KiE in part Ki En la leyla X10-3) 11.8712 KelA = 3.58103 tre tokie din fort b (KEB) = 1 (2X103) (3.742 [(kEz) = 13.98x10-3J. / Ane Tol Clearly in case A has more.
