A small block with mass m slides across africtionless horizontal tabletop and undergoes an elastic collision with a large block with mass 50 m which isinitially at rest.i. Does the small block have a larger, a smaller, orthe same change in the magnitude ofits momentum as the large block? explainii. Does the small block have a larger, a smaller, orthe same change in the magnitude ofits kinetic energy as the largeblock? explain
