This is a physics problem.
The law is that the momentum is preserved: total momentum before collsion = total momentum after collision
Momentum before collision = 80 kg.m/s - 100 kg.m/s = -20 kg.m/s
Then answer is b. - 20 kg.m/s
Answer:
Step-by-step explanation:
Hey There!
8x^46=8x(40+
We move all terms to the left:
8x^46-(8x(40+)=0
Foil
15+6i-20i-8i^2
-8i^2=8
15+8+6i-20i
23-14i
Answer:The answer is 77.
