7. in each system below, player #84 is running at a speed of 7 miles per hour. considering both objects that are about to collide in each system, choose which system you would predict to have the least amount of peak forces.\nsystem a\nsystem b\nsystem c\na player #84 running and heading the soccer ball that was kicked by another player.\nb player #84 running and colliding with another running player running towards them.\nc player #84 running and hitting the ground.
Answer
Explanation:
Step1: Analyze mass - force relationship
Force is related to mass and acceleration (F = ma). The mass of the soccer ball is much less than the mass of another player or the effective mass when hitting the ground.
Step2: Consider collision scenarios
In System A, the collision is between a player and a light - weight soccer ball. In System B, it's between two players of similar mass. In System C, it's between a player and the ground (which has effectively infinite mass compared to the player). A lighter - mass object in collision will generally result in less peak force when the velocities are similar.
Answer:
A. Player #84 running and heading the soccer ball that was kicked by another player.
