Question

1. after hockey practice, carissa and keenan were playing a game where they were pushing some objects to get them to crash. they were using a cone and two different pucks - a black one with more mass for crash 1 and a blue one with less mass for crash 2. they want to know what happened to the cone. use the information from the diagram to answer. in which crash did the cone experience a stronger force? how do you know? a there was no force on the cone. in both crashes, only the hockey puck experienced a force. b the diagram doesnt tell you anything about the force on the cone. it only gives information about the force on the pucks. d crash 1; the force on the black hockey puck was stronger in this crash, so the force on the cone was also stronger. c it was the same force in both crashes; the hockey puck changed speed by the same amount in each crash, so the force on the cone was the same each time.

Explanation:

Step1: Analyze Newton's Third Law

Newton's Third Law states that for every action, there is an equal and opposite reaction. When the hockey puck exerts a force on the cone, the cone exerts an equal force back on the puck.

Step2: Consider force relationship

The force on the puck and the force on the cone are a pair of action - reaction forces. If the force on the puck is stronger (as in Crash 1 with the more massive black puck, assuming a greater change in the puck's motion implies a greater force exerted on it, and by Newton's Third Law, a greater force on the cone), then the force on the cone is also stronger.

Answer:

D. Crash 1; the force on the black hockey puck was stronger in this crash, so the force on the cone was also stronger.
