AFTER COLLISION
a) for first body
V1f = (m1-m2)*Vo1/(m1+m2) +(2*m2*u2/(m1+m2))
V1f = (2-250)*55/(2+250) + 0
V1f = -54.12 m/s
for second body
V2f = (2*m1*Vo1)/(m1+m2)
V2f = (2*2*55)/(2+250) = 0.873 m/s
b)
for first body
V1f = (m1-m2)*Vo1/(m1+m2) +(2*m2*u2/(m1+m2))
V1f = (12-1)*20/(12+1) - (2*1*10)/(1+12)
V1f = 16.9 - 1.54
V1f = 15.36 m/s
For second body
V2f = (2*m1*u1)/(m1+m2) - (m2-m1)*Vo2/(m1+m2)
V2f = ((2*12*20)/(1+12))+((1-12)*10/(1+12))
V2f = 28.46 m/s
c) for first body
V1f = (m1-m2)*Vo1/(m1+m2) +(2*m2*Vo2/(m1+m2))
V1f = (24.5-24.5)*35.7/(24.5+2.45) + 0
V1f = 0 m/s
For second body
V2f = 2*m1*Vo1/(m1+m2)
V2f = (2*24.5*35.7)/(24.5+24.5) = 35.7 m/s
