Calculating Motion of a Test Balloon on a Methane Planet

Click For Summary

Homework Help Overview

The problem involves calculating the motion of a test balloon on a methane planet, which has a gaseous atmosphere and a liquid methane surface. The balloon, filled with helium, is attached to a box of test equipment by a rope, and the scenario requires analyzing the forces acting on both the balloon and the box as they interact with the planet's atmosphere and liquid methane.

Discussion Character

  • Exploratory, Assumption checking, Conceptual clarification

Approaches and Questions Raised

  • Participants discuss the calculation of gravitational acceleration for the planet and the implications of the planet's density. There are questions about which densities to consider and how they affect the buoyant forces acting on the balloon and box. Some participants suggest making diagrams to visualize the problem.

Discussion Status

The discussion is ongoing, with various participants exploring different interpretations of the forces at play. Some have provided calculations for buoyant forces and gravitational acceleration, while others are questioning assumptions about the motion of the balloon and box. There is no explicit consensus yet, but several productive lines of inquiry are being pursued.

Contextual Notes

Participants are navigating the complexities of buoyant forces in both the atmosphere and liquid methane, as well as the effects of density on the motion of the balloon and box. The problem constraints include the need to consider the specific scenario where the box is submerged in liquid methane while the balloon is at the surface.

y=0.5 at² = 0.5* 1.8m/s²*t²
t²= 10m/(0.5*1.8m/s²)=11.11s²
t=3.33s.
Looks right
