Physics Question pertaining to Velocity and Gravity

AI Thread Summary
The discussion revolves around the physics of two identical eggs dropped from rest, one on Earth and the other on the Moon, highlighting the effects of gravity and air resistance. The egg on Earth experiences air resistance, described by the equation F=-kv, while the egg on the Moon falls freely without resistance. Key questions include determining the terminal velocity of the egg on Earth, the height from which both eggs must be dropped to hit the ground at the same speed, and the comparison of the constant k at different altitudes. Participants emphasize the importance of showing effort in solving the problem rather than seeking direct answers. Understanding these concepts is crucial for grasping the dynamics of falling objects in varying gravitational environments.

Homework Statement


Two identical eggs of mass 0.1 kg are dropped from rest at height h. One is dropped on Earth and the other on the surface of the moon. Egg dropped on Earth experiences a force due to air resistance (F=-kv) where v is velocity of egg and k is constant of proportinality equal to Ns/m. No forces of resistance on the moon.

Gravity on Earth = 9.81 m/s^2 Gravity on moon = 1.62 m/s^2





Homework Equations



What is terminal velocity of the egg falling through Earth’s atmosphere?
From what height will the eggs hit the ground at the same speed?
Should the value of k at a high altitude be >, <, or = to k at sea level and why?

Hello Jasonmoon, Welcome to Physics Forums.

What you've written under Relevant Equations is just more of the problem statement, so you should look to identify some equations that you think might be relevant to the problem at hand. You also need to provide some attempt at solving the problem so that we can see what you know about the subject and where you need help. We do not do your homework for you here; you need to show the effort.
 
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...
