Question

1. mateo and jackie were on a playground rolling some different - sized balls to get them to crash. they used a tennis ball (the same mass) in both crashes. they tried two soccer balls—a pink one (more mass) for crash 1 and a blue one (less mass) for crash 2. mateo and jackie want to know what happened to the tennis ball. use information from the diagram to answer. in which crash did the tennis ball experience a stronger force? how do you know? a crash 1: the force on the soccer ball was stronger in this crash, so the force on the tennis ball was also stronger. b there was no force on the tennis ball. in each crash only the soccer ball experienced a force. c it was the same in both crashes. the soccer ball changed speed by the same amount in each crash, so the force on the tennis ball was the same both times. d the diagram doesnt tell you anything about the force on the tennis ball. it only gives information about the force on the soccer balls.

Explanation:

Step1: Recall Newton's third law

For every action, there is an equal - and - opposite reaction.

Step2: Analyze the crashes

In Crash 1, the pink soccer ball has more mass. According to Newton's second law $F = ma$, a more massive object (pink soccer ball in Crash 1) will experience a stronger force for the same acceleration during the collision. Since the forces in a collision are an action - reaction pair, the force on the tennis ball in Crash 1 is also stronger.

Answer:

A. Crash 1; the force on the soccer ball was stronger in this crash, so the force on the tennis ball was also stronger.
