Two cars rolled down a hill with the same steepness. both cars roll 10 m. car A rolled down a wooden hill. car B rolled down the carpeted hill. which car had the slowest speed? how do you know?

Answer 1

Car A rolling down a wooden hill would have the slowest speed compared to car B rolling down a carpeted hill.

Car A rolling down a wooden hill would have the slowest speed compared to car B rolling down a carpeted hill. This is because friction between the wooden hill and the car would slow it down more than the carpeted hill would slow down car B.
