Question

Jami is trying to model the movement of a tire. In order to properly model the movement, she is going to focus on the movement of the tire's air nozzle. The nozzle is on the right side of the tire and she is going to treat that position as the equilibrium position. She then slowly rotates the tire so that the nozzle goes up at the beginning of the rotation, and follows its change in height.

The distance of the nozzle from the center of rotation is nine inches. She finds that it takes eight seconds for the tire to make a single revolution.

Which of the following functions best models the position of the nozzle?

Answer 1

The position of the nozzle of the tyre follows a uniform circular motion.

explanation:

• the angular velocity of the tire is equal to the angular velocity of the nozzle of the tyre. hence the difference in the velocity is attributed due to the difference in the distance of the nozzle from the centre and the diameter of the wheel. due to the circular motion the nozzle first moves up and then goes down.
• However if the  tyre is moving in a non uniform circular motion then the nozzle will also follow the same type of movement
