Question

This is a review of the discussion in the textbook of the colliding students. Make the simplifying assumption that the two students have the same mass and the same speed. Check all the statements that are correct: The final momentum of the one-student system is nonzero. The Momentum Principle when applied to the two-student system is simply 0-0 and doesn't give us any information. The net force on the two-student system is zero because the interatomic force exerted by student 1 on student 2 is equal in magnitude but opposite in direction to the force exerted by student 2 on student 1 The Momentum Principle can't be applied in this analysis because we have no way of estimating we can estimate from the compression distance in the collision. We're interested in the force exerted on one student, so we apply the Momentum Principle to a system consisting of one student. The final momentum of the two-student system is nonzero. The initial momentum of the one-student system is nonzero. The initial momentum of the two-student system is zero. A good estimate of the initial speed of one of the running students is 0.1 m/s.
