Unformatted text preview: to accelerate. We still, however, use this situation as an example of a twodimensional collision where conservation of momentum holds. Explain why this is the case. 4. For a twodimensional elastic collision, two equations are required to express conservation of momentum, whereas only one equation is required to express conservation of kinetic energy. Explain why this is the case....
