1. Suppose we have two blocks of masses m1 and m2. The block
with mass m1 is moving towards block m2 at speed v. After the
collision, we measure the total kinetic energy and find that the
total kinetic energy after the collision is m2/(m1+m2) less than
the kinetic energy before the collision. Find the final speeds of
the two blocks. What type of collision is this?
2. Explain, in words, how we know that a freely spinning
asteroid in...
