AI Thread Summary
Two balls are released from a height of 3 meters, with one ball moving downward at 6 m/s and the other upward at the same speed. To determine how long it takes for the red ball to reach the floor, equations of motion that incorporate time should be utilized. The relevant equation for this scenario is v^2 = v0^2 + 2a(x - x0), but additional equations may be necessary for a complete solution. The discussion emphasizes the importance of selecting the right equations for free fall motion to solve for time and final velocities. Ultimately, the red ball's upward motion will affect its time to reach the ground compared to the green ball.

Homework Statement


Two balls are are released from a table top of height H = 3m at the same time. The green ball is given an initial velocity v0 = 6 m/s in the downward direction, while the red ball is given an initial velocity v0 = 6 m/s in the upward direction.
How long does it take for the red ball to reach the floor?
Which velocity would be greater when it hits the floor?

Homework Equations


v^2=v0^2+2a(x-x0)

The Attempt at a Solution

There are more equations for free fall motion, other than that one. Have a look at them.

You'll want an equation that uses t, since the problem is asking for time.

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...
