925a bullet of mass m travelling at velocity v has a kinetic energy of ½mv2 when it strikes a ballistic pendulum of mass 1000 grams. The kinetic energy of the twomasses moving together just after the moment of impact is about a thousand times smaller than ½mv2. What has most of the bullets initial kinetic energy beenconverted to?
