How Do You Calculate the Coefficient of Restitution from a Bounce Height?

AI Thread Summary
To calculate the coefficient of restitution (e) from the bounce heights, use the formula e = sqrt(h2/h1), where h1 is the initial height (5m) and h2 is the rebound height (2.5m). In this case, e equals sqrt(2.5/5), which simplifies to sqrt(0.5) or approximately 0.707. Participants emphasize the importance of showing initial problem-solving attempts before seeking assistance. The discussion highlights adherence to forum rules regarding homework help. Understanding the coefficient of restitution is crucial for analyzing elastic collisions.

According to the forum rules, you have show some attempt yourself to solve the problem before anyone can attempt to help with whatever part you don't understand. You left off the 2nd and 3rd parts of the homework template.

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...
