具体是:
A space vehicle made up of two parts is travelling at 230 m/s
the mass of partA is 450kg,the mass of partB is 1200 kg.
an explosion causes the 450 kg part to separate and travel with a final velocity of 280 m/s
What was the magnitude of the impulse on the 1200kg part during the seperation?

the magnitude of the impulse of the sapcce vehicle before explosion (爆炸前宇宙飞船的动量):(450+1200)*230= 379 500 Nm
the magnitude of the impulse of A after explosion(爆炸后A的动量):
450*280=126 000Nm
the magnitude of the impulse of B after explosion(爆炸后B的动量):379500-126000=253500 Nm
1200x+450*280=(1200+450)*230
x=211.25
1/2*1200*(230*230-211.25*211.25)
