1. The problem statement, all variables and given/known data A moderate force will break an egg. However, an egg dropped on the road or sidewalk usually breaks, while one dropped on the grass usually does not break. This difference is because for the egg dropped on the grass: A. the change in momentum is greater B. the change in momentum is less C. the time interval for stopping is greater D. the time interval for stopping is less E. the change in velocity is less 2. Relevant equations vf=(m1v1+m2v2)/(m1+m2) 3. The attempt at a solution My thoughts are that the answer is "E" because the change in velocity is less because when the egg comes in contact with the grass, a perfectly inelastic collision occurs where if the egg hits the sidewalk, it is only an inelastic equation. Are my thoughts right, or is it a different answer?
