Question

1. -/2 pointsthe total momentum of a closed system is observed to be 280 kg·m/s east. the system consists of 73 objects that are observed to be colliding with each other. after 23.8 m and 9451 collisions, what is the total momentum of the system?kg·m/s forwards down east left right west up north backwards south

Explanation:

Step1: Recall the law of conservation of momentum

In a closed system (a system with no external forces acting on it), the total momentum is conserved.

Step2: Apply the law to the given problem

Since the system is closed, after any number of collisions (in this case, 9451 collisions), the total momentum remains the same as the initial momentum.

Answer:

280 kg·m/s east
