Hilda rolled a ball across four different surfaces. She rolled the ball with the same amount of force each time. She recorded the time it took for the ball to stop in the chart. Why did the ball roll across the concrete for the longest time?

• because concrete is rougher than the others

• because concrete gets hotter than the others

• because concrete is smoother than the others

• because concrete looks darker than the others
