Question

Two particles, each of mass M and speed v, move as shown. They simultaneously strike the ends of a uniform rod at rest, of mass M and length d which is pivoted at its center. The particles stick to the ends of the rod. Find the ratio of total initial kinetic energy of the two particles plus rod system with the total loss in kinetic energy during collision ?

Initial KE is Mv². Angular momentum about pivot gives final rotational KE Mv²/7. Loss is 6Mv²/7, so initial KE divided by loss is 7/6; the requested grid value is 7.
