B. The speed of the roller coaster will decrease
C. The speed of the roller coaster will remain constant.

Answer 1

B

Step-by-step explanation:

Friction opposes motion therefore reducing motion

Answer 2

Answer: B. The speed will decrease.

Step-by-step explanation:

When you ride a roller coaster, the wheels rub/scrape the rails, creating heat as a result of friction. And friction will slow you down. So increasing the friction on a roller coaster would slow it down.
