Man in a Balloon Homework: Velocity & Movement

AI Thread Summary
The problem involves a man climbing a rope attached to a stationary balloon, creating a closed system with no external forces acting on it. When the man climbs with velocity v relative to the rope, the balloon will experience a reaction, causing it to move in the opposite direction. The system's total momentum remains constant, which is crucial for determining the balloon's velocity. Once the man stops climbing, the system will stabilize, and the balloon will return to its original position. Understanding the principles of conservation of momentum is key to solving this problem.

Homework Statement



a man with mass m hangs from a rope from an air baloon with mass M. the air baloon is not moving with respect t the ground.
In what direction and what is the magnitude of the velocity to the balloon if the man starts climping the rope with a velocity v with respect to the rope?
What happens with the movement of the system when the man stops climing?

Homework Equations



Not sure what equations are relevant

The Attempt at a Solution



I have no idea how to approach this, if anyone could give me some hints on how to solve this, that would be great.

Hi VitaX! :smile:

The man-and-balloon is a closed system with no external forces (or to be precise the extrernal forces are gravity and air pressure, and they balance out to zero) …

soooo … ? :wink:​

Thread 'Minimum mass of a block'

Here we know that if block B is going to move up or just be at the verge of moving up ##Mg \sin \theta ## will act downwards and maximum static friction will act downwards ## \mu Mg \cos \theta ## Now what im confused by is how will we know " how quickly" block B reaches its maximum static friction value without any numbers, the suggested solution says that when block A is at its maximum extension, then block B will start to move up but with a certain set of values couldn't block A reach...

Thread 'Electric field due to charges between 2 parallel infinite planes'

TL;DR Summary: Find Electric field due to charges between 2 parallel infinite planes using Gauss law at any point Here's the diagram. We have a uniform p (rho) density of charges between 2 infinite planes in the cartesian coordinates system. I used a cube of thickness a that spans from z=-a/2 to z=a/2 as a Gaussian surface, each side of the cube has area A. I know that the field depends only on z since there is translational invariance in x and y directions because the planes are...
