Linear Motion Question: Ball thrown in the air

AI Thread Summary
The discussion centers on a physics problem involving a ball thrown upwards from a height of 2x with an initial velocity of v1, and its velocity upon hitting the ground is -v2. Participants question the clarity of the problem, particularly regarding the height of the ball at maximum speed, suggesting it would be at 0x when it impacts the ground. There is also a suggestion that the problem is poorly worded, leading to confusion. The need for a structured homework template is mentioned to clarify the problem further. Overall, the consensus is that the ball reaches maximum speed at ground level, indicating a height of 0x.

A ball is thrown upwards from a building of height 2x with an initial velocity of v1. The velocity when it hits the ground is -v2. What is the height of the ball when it is at maximum speed?

Since it is at its max speed when it hits the ground, would the answer just be 0x?

You should be using the homework template, but yes, you are right. This is a ridiculously stated problem. Are you sure you copied it over correctly?

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...
