An ball bearing of mass m rolls along a horizontal rail at velocity vo and strikes a stationary ball bearing of mass M, which then recoils with a velocity v1 after a perfectly elastic collision. By considering special cases for the relative values of m and M, you can determine which of the following expressions for v1 is correct. You should not need to solve equations for the whole system. v1 = v0 M/m v1 = 2 vo m/M v1= v0 m/(m+M) v1 = 2 vo m/(m+M)
