Two blocks of masses m1 and m2 approach each other on a horizontal table with the same constant speed, v0, as measured by a laboratory observer. The blocks undergo a perfectly elastic collision, and it is observed that m1 stops but m2 moves opposite its original motion with some constant speed, v.

Determine the ratio of the two masses, m1/ m2.

I know the velocity ration is 2, not sure of the other

• physics -

The mass ratio is 3.
