The image depicts a car navigating a vertical loop, demonstrating concepts of physics such as centripetal force and gravity. **Diagram Explanation:** 1. **Position of the Car:** - The diagram shows a car at three distinct positions on a circular track: the top, side, and bottom. 2. **Arrows Indicating Forces:** - **Top Position:** The car is upside down. A blue arrow points left, indicating the direction of motion and the force required to maintain its path. - **Side Position (right):** The car is shown moving upwards. A blue arrow points upward, demonstrating the necessity of upward force to maintain its upward trajectory against gravity. - **Bottom Position:** The car is upright. A blue arrow points right, illustrating the continued forward motion direction. **Educational Context:** This diagram is useful for teaching students about the dynamics of circular motion, the application of centripetal force, and how gravity affects objects in motion. Understanding these principles is fundamental in physics, especially when analyzing real-world applications such as roller coasters and vehicular motion on curved paths.

In a loop-the-loop ride a car goes around a vertical, circular loop at a constant speed. The car has a mass m = 236 kg and moves with speed v = 17.4 m/s. The loop-the-loop has a radius of R = 11.9 m.

 

What is the magnitude of the normal force on the care when it is at the bottom of the circle? (But as the car is accelerating upward.)
N 
 

 

What is the magnitude of the normal force on the car when it is at the side of the circle (moving vertically upward)?
