Correct answer
9
Step-by-step explanation
The distance traversed in the second is given by .
For the first mass ( kg, m/s):
m/s
For the second mass ( kg, m/s):
m/s
Velocities of the masses after s:
m/s
m/s
Momenta of the masses after s:
kg m/s
kg m/s
Ratio of their momenta:
Comparing with , we get .
