Since for a particle the kinetic energy is given by and the momentum by it is easy to show that K =? /2m. How, then, is it possible to have an event during which the total momentum of the system is constant but the total kinetic energy changes?

Solution 10DQ Introduction We have to discuss why kinetic energy changes while keeping momentum constant. Step 1 This is possible because the kinetic energy is not linear function of momentum rather it is the quadratic function. We can divide in two or more parts keeping the momentum same, that is suppose P is the initial momentum then we can divide it in n parts...
