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. 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. d crash 1: the force on the black hockey puck was stronger in this crash, so the force on the cone was also stronger.

Explanation:

Step1: Recall Newton's third - law

For every action, there is an equal and opposite reaction. When the hockey puck hits the cone, the force exerted by the puck on the cone is equal in magnitude and opposite in direction to the force exerted by the cone on the puck.

Step2: Analyze mass and force relationship

The black hockey puck has more mass. According to Newton's second - law $F = ma$ (assuming similar acceleration situations for the pucks during the crashes), a more massive object (the black puck in Crash 1) will experience and exert a stronger force during the collision. Since the force on the cone is equal and opposite to the force exerted by the puck on the cone, the cone experiences a stronger force in Crash 1.

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.
