Chen is testing the friction of three surfaces. He pushes the same ball across three different surfaces with the same force and measures the distance the ball rolls over each surfacel. The ball moved ten inches across Surface 1, six inches across Surface 2, and fifteen inches across Surface 3.
Answer
A
Surface 1 is ice, Surface 2 is gravel, and Surface 3 is blacktop.
B
Surface 1 is gravel, Surface 2 is ice, and Surface 3 is blacktop.
C
Surface 1 is blacktop, Surface 2 is gravel, and Surface 3 is ice.
D
Surface 1 is blacktop, Surface 2 is ice, and Surface 3 is gravel.
Explanation
With the same ball and push, it rolls farther on a surface with less friction. Surface 3 has the greatest distance (15 inches), so it is ice; Surface 2 has the shortest distance (6 inches), so it is gravel. That leaves Surface 1 (10 inches) as blacktop, matching choice C.
