Two objects with masses represented by m1 and m2 approach each other on a horizontal frictionless table with the same constant speed, v0, as measured by a laboratory observer. The objects undergo a perfectly elastic collision, and it is observed that after the collision, m2 moves off in a direction opposite its original motion with some constant speed v, and m1 is stationary.

(a) Determine the ratio of the two masses, m1/m2.

(b) Determine the ratio of their speeds, v/v0.
