SUMMARY

The discussion revolves around a physics homework problem involving a man with mass m climbing a rope attached to a stationary air balloon with mass M. The key question is to determine the direction and magnitude of the balloon's velocity when the man climbs with a velocity v relative to the rope. The system is identified as a closed system where external forces, such as gravity and air pressure, balance out, leading to specific implications for the movement of the balloon when the man ceases climbing.

PREREQUISITES
  • Understanding of closed systems in physics
  • Knowledge of Newton's laws of motion
  • Familiarity with concepts of velocity and relative motion
  • Basic grasp of forces acting on objects (gravity and air pressure)
NEXT STEPS
  • Study the principles of conservation of momentum in closed systems
  • Learn about relative velocity and its applications in physics
  • Explore the effects of external forces on stationary systems
  • Review examples of similar problems involving mass and movement in physics
USEFUL FOR

Students studying physics, particularly those tackling problems related to mechanics and motion, as well as educators seeking to explain concepts of relative velocity and closed systems.

Homework Statement



a man with mass m hangs from a rope from an air balloon with mass M. the air balloon 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:​
