Siti released a toy car from the top of a ramp. She measured the distance travelled by the car on four different surfaces. Which surface likely provided the MOST frictional force?

A Surface X: 85 cm
B Surface Y: 40 cm
C Surface Z: 150 cm
D Surface W: 120 cm

Worked Solution

Step 1: Identify the relationship between friction and distance (Higher friction = shorter distance). Step 2: Compare distances: 40 cm is the shortest. Step 3: Therefore, Surface Y provides the most friction.

Correct answer: Surface Y: 40 cm
