Question

ust snow all work, step-by-step to receive credit on problems 11 and 12. 11) Four objects undergo a simultaneous co objects undergo a simultaneous collision. Their configuration just before the collision is shown. If they stick together during the collision, what will be the final velocity of the combined object? The values are mi = 12kg, m2 = 13kg, m3 = 11.5kg, m4 = 12.5kg, Vi = 12m/s, v2 = 13m/s, V3 = 19m/s, 14 = 11m/s. mi P = PE mhm

Answer 1

momentum of the system in conserved before and after collision Pinitial = -12X12 1 - 13813 i +11,5 x 19+125 XIL (74.5 ; - $31.5 i Igm/s Pfinal = (12 + B + 11.5 + 12.5) To = 49 te leggy's b Pinitial - Pfinal khung - ł=74.5; -3. s e =[ 0.641 + 1-52j) m/s () = 1.649 m/s 49
