Projectile motion only provided acceleration diatance

AI Thread Summary
To determine the initial vertically upward speed and horizontal speed of a projectile, it's essential to differentiate between vertical and horizontal displacements. The vertical displacement only accounts for the distance from launch to maximum height, while the horizontal displacement covers the entire trajectory. It is crucial to recognize that only horizontal acceleration is zero, necessitating the use of equations that incorporate vertical acceleration. The discussion highlights a common misunderstanding in applying these principles to solve projectile motion problems. Accurate calculations require careful attention to these distinctions.

1. You have mixed up vertical and horizontal displacements.
2. The given vertical displacement is from launch to max height, but the given horizontal displacement is for the whole trajectory.
3. Only the horizontal acceleration is zero. You need an equation involving vertical acceleration.

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...
