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 strength force because they both gained force, but the blue curling stone lost force.

Explanation:

Step1: Analyze the relationship between force and change in speed

According to Newton's second law \(F = ma\) (where \(F\) is force, \(m\) is mass, and \(a\) is acceleration, and acceleration \(a=\frac{\Delta v}{\Delta t}\), \(\Delta v\) is the change in velocity). A larger change in speed (\(\Delta v\)) for the same mass \(m\) and time \(\Delta t\) implies a larger force \(F\).

Step2: Compare the change in speed of each stone

The blue curling stone changed speed the most. Since \(F = ma\) and \(m\) (mass) is the same for all stones (given in the problem), a larger \(\Delta v\) (change in speed) means a larger force \(F\) (because \(a=\frac{\Delta v}{\Delta t}\) and \(F = ma\)).

Answer:

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