Roller Coaster Problem Help NEEDED

AI Thread Summary
To determine the apparent weight of a rider at the bottom of a vertical loop with a radius of 5.40 m, the problem involves multiple calculations, including the speed at various points on the coaster. The user is confused about using conservation of energy to find the mass, as it seems to yield zero due to a lack of height change. Clarification on how to approach the calculations, particularly for the third part, is requested. The discussion emphasizes the need for guidance on applying physics principles effectively. Understanding the forces at play, especially centripetal force, is crucial for solving the problem.

Homework Statement


Suppose the vertical loop has a radius of 5.40 m. What is the apparent weight (Wap) of a rider on the roller coaster at the bottom of the loop? (Assume that friction between roller coaster and rails can be neglected. Give your answer in terms of m and g.)




Homework Equations



NA

The Attempt at a Solution


this problem was very long and it had like 5 parts to it. 1st part was to calculate the speed on the top of coaster . Second part was to calculate the speed at several different points.
The third part has gotten me a little confused. I was thinkink about using the conservation of energy to calculate the mass but there is no this confuses me because it turns out to be zero because there is no initial height or final height.

SO any advice or tips or hints on how to start would be great !

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
