Question

8. A scientist designed an investigation to measure the distance required to stop a car on several different road surfaces. The car was traveling at a speed of 10 m/s at the beginning of each trial. Below are the results of her investigation. Which conclusion is best supported by the data from her investigation? The force of friction is greatest on asphalt. The forward force from the engine was greatest on ice. The forward force from the engine was greatest on asphalt. The force of friction is greatest on ice.

Answer 1

The force of friction is greatest on asphalt.

Step-by-step explanation:

The friction is a force which help to stop an object on a slippery surface. The friction on ice is very low therefore vehicles are unable to stop on ice quickly and they slip. The ice has slippery surface and there need strong friction to stop an object on the ice.
