Code:
A B
--> <--
24kgm/s 10kgm/s
Two trucks A and B are about to collide head on; their values of linear momentum are as shown in the figure above. After the collision the two trucks separate and move away from each other, at which time truck A has a linear momentum of 8.0 kgm/s.
My answer was 22 kgm/s because I assumed in my calculations that A and B will move in opposite directions after the collision, as this is what I infer from the statement 'after the collision the two trucks separate and move away from each other'.
However, this is wrong and the answer given in the book is 6 kgm/s.
I'm not sure what to make of this. Can someone please explain?
