Dirac Wednesday , October 20, 2010 Multiple Choice Questions on Elastic and Inelastic Collisions Today we will discuss two questions on collisions . The first question pertains to elastic collision in one dimension and the second question pertains to inelastic collision in two : dimensions 1 A particle A of mass m moving along the positive x-direction with kinetic energy K suffers an elastic head-on collision with a stationary particle B of mass M After the collision the particle A moves along the negative x-direction with kinetic energy K 9. What is the
