GR0877 Problem 29

PROBLEM STATEMENT: This problem is still being typed.

SOLUTION: (C) In elastic collisions energy is conserved. So Mv^2/2 = M(v/2)^2/2 +Mu^2/2 from which one has u = \frac{\sqrt{3}}{2} v.

    Why doesn’t conservation of momentum give the same result for this problem?

      Yeah I have the same problem! Using momentum conservation, I get choice E but with a minus sign in between. So, since my answer isn’t any of the choices, i would used E conservation.
