Asked by Kelly
Consider a ballistic pendulum experiment in which the mass of the ball (bullet) and the pendulum cage (block) are the same. What would be the expected percentage loss of kinetic energy in this experiment?

well, you double the mass, and halve the velocity, so KE changes by a factor of 2*(1/2)^2=1/4
So you lost 3/4 of the original KE
So you lost 3/4 of the original KE
