Answer:
0 kg*m/s
Step-by-step explanation:
The law of conservation of momentum states that the total momentum of a closed system is conserved. It means that the sum of momentum of individual objects in a closed system remains the same throughout.
For this system, the total momentum of the system before collision is +25+35= +60;
After collision:
60 = momentum of block A + momentum of block B
60=60+x, where x is the momentum of block B. Evaluate x.
