Asked by √ ∙ ÷ ≤ ≠

A student is investigating how the type of surface affects how far a toy car rolls after being released down a ramp.

The student tests four different surfaces at the bottom of the ramp:

Surface A: Smooth tile

Surface B: Sandpaper

Surface C: Carpet

Surface D: Wood floor

They release the same toy car from the same height each time and measure the distance the car travels after it leaves the ramp.

Here are the results:

Surface

A

C

D

Distance Traveled (cm)
120
35
50
100

Based on the data, which surface has the least amount of friction, and what evidence supports this conclusion?

(1 point)

O Surface A, because the car traveled the shortest distance.

O Surface B, because the car traveled the farthest.

O Surface A, because the car traveled the farthest.

Surface C, because it is soft and slows the car down.
