Question
### Tire Rotation and Speed Calculation **Problem Overview:** A car tire has a diameter of 55.0 cm. The car is traveling at a speed of 24.0 m/s. --- **Part A: Tire's Rotation Frequency** **Question:** What is the tire's rotation frequency in rpm (revolutions per minute)? **Explanation:** 1. **Formula to Use:** \[ \text{Rotation frequency (rpm)} = \left( \frac{\text{linear speed (m/s)}}{\text{circumference of the tire (m)}} \right) \times 60 \] 2. **Circumference Calculation:** Given diameter = 55.0 cm = 0.55 m; \[ \text{Circumference} = \pi \times 0.55 \] 3. **Substitute the Values:** - Linear speed = 24.0 m/s - Calculate and substitute to find the rotation frequency. 4. **User Response:** - The user attempted an answer: 706 rpm. - Feedback: Incorrect; the user has three attempts remaining. --- **Part B: Speed at the Top Edge of the Tire** **Question:** What is the speed of a point at the top edge of the tire? **Explanation:** 1. **Concept:** - The top edge of a rotating tire moves at the speed of the car plus the speed of the tire's rotation (relative to the ground). - Speed at the top = 2 x car speed 2. **Calculation:** - Given car speed = 24.0 m/s - Speed at the top = 48.0 m/s 3. **User Response:** - The user entered: 48.0 m/s. - Feedback: Correct. --- This exercise requires understanding the relationship between linear speed, rotational speed, and how they relate to tire mechanics in physics.
