Launching projectile from north pole to equator

AI Thread Summary
To launch a projectile from the North Pole to land on the equator, a velocity of approximately 9.5 km/s is necessary, though this is a high requirement. A launch angle of 45 degrees is often considered optimal for maximum range, but achieving this trajectory involves complex calculations beyond simple physics. The projectile's path would be sub-orbital, meaning it would not maintain a stable orbit. Air friction and other environmental factors must also be taken into account, complicating the calculations further. Overall, the task requires careful consideration of physics principles and real-world conditions.

I am trying to find what velocity and angle of launch is required for a projectile to be fired from the North pole and land somewhere on the equator. I was thinking 45 degrees with muzzle velocity 9401m/s but that sounds ridiculous. Also how much time would it be in the air for?

Are you neglecting air friction?

This isn't a simple plug and chug. That path will be sub-orbital.

9.5 km/sec is high, but you're in the right ballpark.

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...
