Rolling ball Free fall question

AI Thread Summary
The discussion centers on a physics problem involving a ball rolling off a table at two different speeds. The first ball, moving at 1.0 m/s, takes 0.50 seconds to hit the floor after leaving the edge. Participants confirm that the second ball, rolling at 2.0 m/s, will also take 0.50 seconds to reach the ground. This conclusion is based on the principle that horizontal and vertical motions are independent of each other. The key takeaway is that the time to fall remains constant regardless of the horizontal speed.

Homework Statement


A ball moving with constant speed 1.0 m/s on a horizontal table rolls off the edge of the table. The ball hits the floor 0.50 seconds after leaving the edge. Suppose you roll the same ball on the same table with constant speed 2.0 m/s. After leaving the edge of the table, how long does it for this faster ball to hit the floor? Neglect air friction.


Homework Equations





The Attempt at a Solution


It would take the second ball .5 seconds just like the first ball because the x and y motions are independent of each other, right?

Correct.

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...
