Question

1. curling is a sport in which players push large stones across smooth ice. three curling stones that have the same mass were sliding across the ice. they were each pushed by a player, but not all from the same direction. each curling stone changed speed as a result of being hit. use the information in the diagram to answer. which curling stone(s) experienced the strongest force when hit? how do you know? a the blue curling stone experienced the strongest force because it takes a stronger force to slow something down than it takes to speed something up. b the blue curling stone experienced the strongest force because it changed speed the most. c the orange curling stone experienced the strongest force because it has the fastest ending speed. d the yellow and orange curling stones experienced the same strong force because they both gained force, but the blue curling stone lost force.

Explanation:

Step1: Recall Newton's second law

Force $F = ma$, where $m$ is mass and $a$ is acceleration. Acceleration is the change in speed over time.

Step2: Analyze given situation

The stones have the same mass. The greater the change in speed, the greater the acceleration. Since $F = ma$ and $m$ is constant, a larger - acceleration means a larger force. The blue stone changed speed the most, so it experienced the strongest force.

Answer:

B. The blue curling stone experienced the strongest force because it changed speed the most.
