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 of each ball. the ball moved ten inches across surface 1, six inches across surface 2, and fifteen inches across surface 3.
which could most likely describe the three surfaces?
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.
