Circular motion-what is the radius of the loop de loop in meters

AI Thread Summary
Snoopy's warplane is performing a loop de loop at a speed of 180 km/hr, which converts to 50 m/s. While at the bottom of the loop, he experiences a weight four times his normal weight, indicating a net upward force contributing to centripetal acceleration. The net force acting on him is calculated as 3mg, leading to an acceleration of 29.4 m/s². Using the centripetal acceleration formula, the radius of the loop is determined to be approximately 85 meters. The discussion emphasizes the importance of identifying forces and applying Newton's laws to solve for the radius in circular motion problems.
