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
The final awser is x-16
hope this is what u needed
63/240 seats or 21/80
The greatest common denominator is 3, so you would divide both by 3.
