Final answer:
Cyclists at the 2016 Summer Olympics experienced rolling friction and air resistance; rolling friction involves static friction for rolling without slipping, and air resistance opposes their forward motion.
Step-by-step explanation:
At the 2016 Summer Olympics, cyclists in the race would experience both rolling friction and air resistance. Rolling friction occurs when the tires of the bicycle deform slightly as they make contact with the road surface, allowing the tires to roll without slipping. This type of motion requires static friction between the tire and the road surface, which means that the bottom part of the tire is momentarily at rest with respect to the ground while the wheel is in motion. On the other hand, air resistance is a form of friction that acts against the cyclist as they move through the air. Therefore, the correct answer is A) Rolling Friction and Air Resistance. It's important to note that kinetic friction would come into play if the wheels were slipping on the surface, which is not the desired condition for cycling.
